Struct rustc_graphviz::Id

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

Id is a Graphviz ID.

Fields

name: Cow<'a, str>

Implementations

impl<'a> Id<'a>

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.

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.
