## ExpnHashTable

# Type Alias ExpnHashTable

Source

    type ExpnHashTable = LazyTable<ExpnIndex, Option<LazyValue<ExpnHash>>>;

## Aliased Type§

    struct ExpnHashTable {
        position: NonZero<usize>,
        width: usize,
        len: usize,
        _marker: PhantomData<fn(ExpnIndex) -> Option<LazyValue<ExpnHash>>>,
    }

## Fields§

§`position: NonZero<usize>`§`width: usize`

The encoded size of the elements of a table is selected at runtime to drop trailing zeroes. This is the number of bytes used for each table element.

§`len: usize`

How many elements are in the table.

§`_marker: PhantomData<fn(ExpnIndex) -> Option<LazyValue<ExpnHash>>>`

## Layout§

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain `repr(...)` attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
