## Id

# Struct Id

Source

    pub struct Id<'a> {
        pub(crate) name: Cow<'a, str>,
    }

Expand description

`Id` is a Graphviz `ID`.

## Fields§

§`name: Cow<'a, str>`

## Implementations§

Source§

### impl<'a> Id<'a>

Source

#### pub fn new<Name: Into<Cow<'a, str>>>(name: Name) -> Result<Id<'a>, ()>

Creates an `Id` named `name`.

The caller must ensure that the input conforms to an identifier format: it must be a non-empty string made up of alphanumeric or underscore characters, not beginning with a digit (i.e., the regular expression `[a-zA-Z_][a-zA-Z_0-9]*`).

(Note: this format is a strict subset of the `ID` format defined by the DOT language. This function may change in the future to accept a broader subset, or the entirety, of DOT’s `ID` format.)

Passing an invalid string (containing spaces, brackets, quotes, …) will return an empty `Err` value.

Source

#### pub fn as_slice(&'a self) -> &'a str

## 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.
