The 64-bit unsigned integer type.

## Implementations§

Source§

### impl u64

1.43.0 · Source

#### pub const MIN: u64 = 0

The smallest value that can be represented by this integer type.

##### §Examples

    assert_eq!(u64::MIN, 0);

1.43.0 · Source

#### pub const MAX: u64

The largest value that can be represented by this integer type (264 − 1).

##### §Examples

    assert_eq!(u64::MAX, 18446744073709551615);

1.53.0 · Source

#### pub const BITS: u32

The size of this integer type in bits.

##### §Examples

    assert_eq!(u64::BITS, 64);

1.0.0 (const: 1.32.0) · Source

#### pub const fn count_ones(self) -> u32

Returns the number of ones in the binary representation of `self`.

##### §Examples

    let n = 0b01001100u64;
    assert_eq!(n.count_ones(), 3);

    let max = u64::MAX;
    assert_eq!(max.count_ones(), 64);

    let zero = 0u64;
    assert_eq!(zero.count_ones(), 0);

1.0.0 (const: 1.32.0) · Source

#### pub const fn count_zeros(self) -> u32

Returns the number of zeros in the binary representation of `self`.

##### §Examples

    let zero = 0u64;
    assert_eq!(zero.count_zeros(), 64);

    let max = u64::MAX;
    assert_eq!(max.count_zeros(), 0);

This is heavily dependent on the width of the type, and thus might give surprising results depending on type inference:

    let lucky = 7;
    foo(lucky);
    assert_eq!(lucky.count_zeros(), 5);
    assert_eq!(lucky.count_ones(), 3);

    let lucky = 7;
    bar(lucky);
    assert_eq!(lucky.count_zeros(), 13);
    assert_eq!(lucky.count_ones(), 3);

You might want to use `Self::count_ones` instead, or emphasize the type you’re using in the call rather than method syntax:

    let small = 1;
    assert_eq!(u64::count_zeros(small), 63);

1.0.0 (const: 1.32.0) · Source

#### pub const fn leading_zeros(self) -> u32

    assert_eq!(n.leading_zeros(), 2);

    let zero = 0u64;
    assert_eq!(zero.leading_zeros(), 64);

Source

#### pub const fn saturating_cast_signed(self) -> i64

🔬This is a nightly-only experimental API. (`integer_cast_extras` #154650)

Saturating conversion of `self` to a signed integer of the same size.

The signed integer’s maximum value is returned if `self` is larger than the maximum positive value representable by the signed integer.

For other kinds of signed integer casts, see `cast_signed`, `checked_cast_signed`, or `strict_cast_signed`.

##### §Examples

    #![feature(integer_cast_extras)]
    let n = u64::MAX;

    assert_eq!(n.saturating_cast_signed(), i64::MAX);

#### pub const fn rotate_left(self, n: u32) -> u64

Shifts the bits to the left by a specified amount, `n`, wrapping the truncated bits to the end of the resulting integer.

`rotate_left(n)` is equivalent to applying `rotate_left(1)` a total of `n` times. In particular, a rotation by the number of bits in `self` returns the input value unchanged.

Please note this isn’t the same operation as the `<<` shifting operator!

##### §Examples

    let n = 0xaa00000000006e1u64;
    let m = 0x6e10aa;

    assert_eq!(n.rotate_left(12), m);
    assert_eq!(n.rotate_left(1024), n);

1.0.0 (const: 1.32.0) · Source

#### pub const fn rotate_right(self, n: u32) -> u64

Shifts the bits to the right by a specified amount, `n`, wrapping the truncated bits to the beginning of the resulting integer.

`rotate_right(n)` is equivalent to applying `rotate_right(1)` a total of `n` times. In particular, a rotation by the number of bits in `self` returns the input value unchanged.

Please note this isn’t the same operation as the `>>` shifting operator!

##### §Examples

    let n = 0x6e10aau64;
    let m = 0xaa00000000006e1;

    assert_eq!(n.rotate_right(12), m);
    assert_eq!(n.rotate_right(1024), n);

Source

#### pub const fn funnel_shl(self, rhs: u64, n: u32) -> u64

🔬This is a nightly-only experimental API. (`funnel_shifts` #145686)

Performs a left funnel shift (concatenates `self` with `rhs`, with `self` making up the most significant half, then shifts the combined value left by `n`, and most significant half is extracted to produce the result).

Please note this isn’t the same operation as the `<<` shifting operator or `rotate_left`, although `a.funnel_shl(a, n)` is equivalent to `a.rotate_left(n)`.

##### §Panics

If `n` is greater than or equal to the number of bits in `self`

##### §Examples

Basic usage:

    #![feature(funnel_shifts)]
    let a = 0xaa00000000006e1u64;
    let b = 0x2fe78e45983acd98u64;
    let m = 0x6e12fe;

    assert_eq!(a.funnel_shl(b, 12), m);

Source

#### pub const fn funnel_shr(self, rhs: u64, n: u32) -> u64

🔬This is a nightly-only experimental API. (`funnel_shifts` #145686)

Performs a right funnel shift (concatenates `self` and `rhs`, with `self` making up the most significant half, then shifts the combined value right by `n`, and least significant half is extracted to produce the result).

Please note this isn’t the same operation as the `>>` shifting operator or `rotate_right`, although `a.funnel_shr(a, n)` is equivalent to `a.rotate_right(n)`.

##### §Panics

If `n` is greater than or equal to the number of bits in `self`

##### §Examples

Basic usage:

    #![feature(funnel_shifts)]
    let a = 0xaa00000000006e1u64;
    let b = 0x2fe78e45983acd98u64;
    let m = 0x6e12fe78e45983ac;

    assert_eq!(a.funnel_shr(b, 12), m);

Source

#### pub const unsafe fn unchecked_funnel_shl(self, low: u64, n: u32) -> u64

🔬This is a nightly-only experimental API. (`funnel_shifts` #145686)

Unchecked funnel shift left.

##### §Safety

This results in undefined behavior if `n` is greater than or equal to `u64::BITS`, i.e. when `funnel_shl` would panic.

Source

#### pub const unsafe fn unchecked_funnel_shr(self, low: u64, n: u32) -> u64

🔬This is a nightly-only experimental API. (`funnel_shifts` #145686)

Unchecked funnel shift right.

##### §Safety

This results in undefined behavior if `n` is greater than or equal to `u64::BITS`, i.e. when `funnel_shr` would panic.

#### pub const fn carryless_mul(self, rhs: u64) -> u64

🔬This is a nightly-only experimental API. (`uint_carryless_mul` #152080)

Performs a carry-less multiplication, returning the lower bits.

This operation is similar to long multiplication in base 2, except that exclusive or is used instead of addition. The implementation is equivalent to:

    pub fn carryless_mul(lhs: u64, rhs: u64) -> u64{
        let mut retval = 0;
        for i in 0..u64::BITS {
            if (rhs >> i) & 1 != 0 {
                // long multiplication would use +=
                retval ^= lhs << i;
            }
        }
        retval
    }

The actual implementation is more efficient, and on some platforms lowers directly to a dedicated instruction.

##### §Uses

Carryless multiplication can be used to turn a bitmask of quote characters into a bit mask of characters surrounded by quotes:

    r#"abc xxx "foobar" zzz "a"!"#; // input string
     0b0000000010000001000001010; // quote_mask
     0b0000000001111110000000100; // quote_mask.carryless_mul(!0) & !quote_mask

Another use is in cryptography, where carryless multiplication allows for efficient implementations of polynomial multiplication in `GF(2)[X]`, the polynomial ring over `GF(2)`.

##### §Examples

    #![feature(uint_carryless_mul)]

    let a = 0x7890123456789012u64;
    let b = 0xdd358416f52ecd34u64;

    assert_eq!(a.carryless_mul(b), 0xa6299579b980928);

    assert_eq!(n.extract_bits(0xF0), 0b0000_1011);

Source

#### pub const fn deposit_bits(self, mask: u64) -> u64

🔬This is a nightly-only experimental API. (`uint_gather_scatter_bits` #149069)

Returns an integer with the least significant bits of `self` distributed to the bit locations specified by `mask`.

    #![feature(uint_gather_scatter_bits)]
    let n: u64 = 0b1010_1101;

    let m = n.reverse_bits();

    assert_eq!(m, 0x6a2c48091e6a2c48);

1.79.0 (const: 1.79.0) · Source

#### pub const unsafe fn unchecked_add(self, rhs: u64) -> u64

Unchecked integer addition. Computes `self + rhs`, assuming overflow cannot occur.

Calling `x.unchecked_add(y)` is semantically equivalent to calling `x.``checked_add``(y).``unwrap_unchecked``()`.

If you’re just trying to avoid the panic in debug mode, then do not use this. Instead, you’re looking for `wrapping_add`.

##### §Safety

This results in undefined behavior when `self + rhs > u64::MAX`, i.e. when `checked_add` would return `None`.

Strict integer subtraction. Computes `self - rhs`, panicking if overflow occurred.

##### §Panics

1.79.0 (const: 1.79.0) · Source

#### pub const unsafe fn unchecked_sub(self, rhs: u64) -> u64

Unchecked integer subtraction. Computes `self - rhs`, assuming overflow cannot occur.

Calling `x.unchecked_sub(y)` is semantically equivalent to calling `x.``checked_sub``(y).``unwrap_unchecked``()`.

If you’re just trying to avoid the panic in debug mode, then do not use this. Instead, you’re looking for `wrapping_sub`.

If you find yourself writing code like this:

    if foo >= bar {
        // SAFETY: just checked it will not overflow
        let diff = unsafe { foo.unchecked_sub(bar) };
        // ... use diff ...
    }

Consider changing it to

    if let Some(diff) = foo.checked_sub(bar) {
        // ... use diff ...
    }

As that does exactly the same thing – including telling the optimizer that the subtraction cannot overflow – but avoids needing `unsafe`.

##### §Safety

This results in undefined behavior when `self - rhs < u64::MIN`, i.e. when `checked_sub` would return `None`.

#### pub const unsafe fn unchecked_mul(self, rhs: u64) -> u64

Unchecked integer multiplication. Computes `self * rhs`, assuming overflow cannot occur.

Calling `x.unchecked_mul(y)` is semantically equivalent to calling `x.``checked_mul``(y).``unwrap_unchecked``()`.

If you’re just trying to avoid the panic in debug mode, then do not use this. Instead, you’re looking for `wrapping_mul`.

#### pub const unsafe fn unchecked_disjoint_bitor(self, other: u64) -> u64

🔬This is a nightly-only experimental API. (`disjoint_bitor` #135758)

Same value as `self | other`, but UB if any bit position is set in both inputs.

This is a situational micro-optimization for places where you’d rather use addition on some platforms and bitwise or on other platforms, based on exactly which instructions combine better with whatever else you’re doing. Note that there’s no reason to bother using this for places where it’s clear from the operations involved that they can’t overlap. For example, if you’re combining `u16`s into a `u32` with `((a as u32) << 16) | (b as u32)`, that’s fine, as the backend will know those sides of the `|` are disjoint without needing help.

##### §Examples

    #![feature(disjoint_bitor)]

    // SAFETY: `1` and `4` have no bits in common.
    unsafe {
        assert_eq!(1_u64.unchecked_disjoint_bitor(4), 5);
    }

##### §Safety

Requires that `(self & other) == 0`, otherwise it’s immediate UB.

Equivalently, requires that `(self | other) == (self + other)`.

#### pub const fn wrapping_neg(self) -> u64

Wrapping (modular) negation. Computes `-self`, wrapping around at the boundary of the type.

Since unsigned types do not have negative equivalents all applications of this function will wrap (except for `-0`). For values smaller than the corresponding signed type’s maximum the result is the same as casting the corresponding signed value. Any larger values are equivalent to `MAX + 1 - (val - MAX - 1)` where `MAX` is the corresponding signed type’s maximum.

#### pub const fn wrapping_shl(self, rhs: u32) -> u64

Panic-free bitwise shift-left; yields `self << mask(rhs)`, where `mask` removes any high-order bits of `rhs` that would cause the shift to exceed the bitwidth of the type.

Beware that, unlike most other `wrapping_*` methods on integers, this does not give the same result as doing the shift in infinite precision then truncating as needed. The behaviour matches what shift instructions do on many processors, and is what the `<<` operator does when overflow checks are disabled, but numerically it’s weird. Consider, instead, using `Self::unbounded_shl` which has nicer behaviour.

Note that this is not the same as a rotate-left; the RHS of a wrapping shift-left is restricted to the range of the type, rather than the bits shifted out of the LHS being returned to the other end. The primitive integer types all implement a `rotate_left` function, which may be what you want instead.

#### pub const fn wrapping_shr(self, rhs: u32) -> u64

Panic-free bitwise shift-right; yields `self >> mask(rhs)`, where `mask` removes any high-order bits of `rhs` that would cause the shift to exceed the bitwidth of the type.

#### pub fn carrying_add(self, rhs: u64, carry: bool) -> (u64, bool)

Calculates `self` + `rhs` + `carry` and returns a tuple containing the sum and the output carry (in that order).

Performs “ternary addition” of two integer operands and a carry-in bit, and returns an output integer and a carry-out bit. This allows chaining together multiple additions to create a wider addition, and can be useful for bignum addition.

This can be thought of as a 64-bit “full adder”, in the electronics sense.

If the input carry is false, this method is equivalent to `overflowing_add`, and the output carry is equal to the overflow flag. Note that although carry and overflow flags are similar for unsigned integers, they are different for signed integers.

##### §Examples

    //    3  MAX    (a = 3 × 2^64 + 2^64 - 1)

#### pub fn carrying_mul(self, rhs: u64, carry: u64) -> (u64, u64)

Calculates the “full multiplication” `self * rhs + carry` without the possibility to overflow.

This returns the low-order (wrapping) bits and the high-order (overflow) bits of the result as two separate values, in that order.

Performs “long multiplication” which takes in an extra amount to add, and may return an additional amount of overflow. This allows for chaining together multiple multiplications to create “big integers” which represent larger values.

If you also need to add a value, then use `Self::carrying_mul_add`.

##### §Examples

Please note that this example is shared among integer types, which is why `u32` is used.

    assert_eq!(5u32.carrying_mul(2, 0), (10, 0));
    assert_eq!(5u32.carrying_mul(2, 10), (20, 0));
    assert_eq!(1_000_000_000u32.carrying_mul(10, 0), (1410065408, 2));
    assert_eq!(1_000_000_000u32.carrying_mul(10, 10), (1410065418, 2));
    assert_eq!(u64::MAX.carrying_mul(u64::MAX, u64::MAX), (0, u64::MAX));

This is the core operation needed for scalar multiplication when implementing it for wider-than-native types.

    fn scalar_mul_eq(little_endian_digits: &mut Vec<u16>, multiplicand: u16) {
        let mut carry = 0;
        for d in little_endian_digits.iter_mut() {
            (*d, carry) = d.carrying_mul(multiplicand, carry);
        }
        if carry != 0 {
            little_endian_digits.push(carry);
        }
    }

    let mut v = vec![10, 20];
    scalar_mul_eq(&mut v, 3);
    assert_eq!(v, [30, 60]);

    assert_eq!(0x87654321_u64 * 0xFEED, 0x86D3D159E38D);
    let mut v = vec![0x4321, 0x8765];
    scalar_mul_eq(&mut v, 0xFEED);
    assert_eq!(v, [0xE38D, 0xD159, 0x86D3]);

If `carry` is zero, this is similar to `overflowing_mul`, except that it gives the value of the overflow instead of just whether one happened:

    #![feature(const_unsigned_bigint_helpers)]
    let r = u8::carrying_mul(7, 13, 0);
    assert_eq!((r.0, r.1 != 0), u8::overflowing_mul(7, 13));
    let r = u8::carrying_mul(13, 42, 0);
    assert_eq!((r.0, r.1 != 0), u8::overflowing_mul(13, 42));

The value of the first field in the returned tuple matches what you’d get by combining the `wrapping_mul` and `wrapping_add` methods:

    #![feature(const_unsigned_bigint_helpers)]
    assert_eq!(
        789_u16.carrying_mul(456, 123).0,
        789_u16.wrapping_mul(456).wrapping_add(123),
    );

1.91.0 (const: unstable) · Source

#### pub fn carrying_mul_add(self, rhs: u64, carry: u64, add: u64) -> (u64, u64)

Calculates the “full multiplication” `self * rhs + carry + add`.

This returns the low-order (wrapping) bits and the high-order (overflow) bits of the result as two separate values, in that order.

This cannot overflow, as the double-width result has exactly enough space for the largest possible result. This is equivalent to how, in decimal, 9 × 9 + 9 + 9 = 81 + 18 = 99 = 9×10⁰ + 9×10¹ = 10² - 1.

Performs “long multiplication” which takes in an extra amount to add, and may return an additional amount of overflow. This allows for chaining together multiple multiplications to create “big integers” which represent larger values.

If you don’t need the `add` part, then you can use `Self::carrying_mul` instead.

##### §Examples

Please note that this example is shared between integer types, which explains why `u32` is used here.

    assert_eq!(5u32.carrying_mul_add(2, 0, 0), (10, 0));
    assert_eq!(5u32.carrying_mul_add(2, 10, 10), (30, 0));
    assert_eq!(1_000_000_000u32.carrying_mul_add(10, 0, 0), (1410065408, 2));
    assert_eq!(1_000_000_000u32.carrying_mul_add(10, 10, 10), (1410065428, 2));
    assert_eq!(u64::MAX.carrying_mul_add(u64::MAX, u64::MAX, u64::MAX), (u64::MAX, u64::MAX));

This is the core per-digit operation for “grade school” O(n²) multiplication.

Please note that this example is shared between integer types, using `u8` for simplicity of the demonstration.

    fn quadratic_mul<const N: usize>(a: [u8; N], b: [u8; N]) -> [u8; N] {
        let mut out = [0; N];

#### pub const fn is_multiple_of(self, rhs: u64) -> bool

Returns `true` if `self` is an integer multiple of `rhs`, and false otherwise.

This function is equivalent to `self % rhs == 0`, except that it will not panic for `rhs == 0`. Instead, `0.is_multiple_of(0) == true`, and for any non-zero `n`, `n.is_multiple_of(0) == false`.

#### pub const fn next_power_of_two(self) -> u64

Returns the smallest power of two greater than or equal to `self`.

When return value overflows (i.e., `self > (1 << (N-1))` for type `uN`), it panics in debug mode and the return value is wrapped to 0 in release mode (the only situation in which this method can return 0).
