Struct regex_syntax::ast::Literal

pub struct Literal {
    pub span: Span,
    pub kind: LiteralKind,
    pub c: char,
}

A single literal expression.

A literal corresponds to a single Unicode scalar value. Literals may be represented in their literal form, e.g., a or in their escaped form, e.g., \x61.

Fields

span: Span

The span of this literal.

kind: LiteralKind

The kind of this literal.

c: char

The Unicode scalar value corresponding to this literal.

Implementations

impl Literal

pub fn byte(&self) -> Option<u8>

If this literal was written as a \x hex escape, then this returns the corresponding byte value. Otherwise, this returns None.

Trait Implementations

impl<'arbitrary> Arbitrary<'arbitrary> for Literal

fn arbitrary(u: &mut Unstructured<'arbitrary>) -> Result<Self>

Generate an arbitrary value of Self from the given unstructured data.

fn arbitrary_take_rest(u: Unstructured<'arbitrary>) -> Result<Self>

Generate an arbitrary value of Self from the entirety of the given unstructured data.

fn size_hint(depth: usize) -> (usize, Option<usize>)

Get a size hint for how many bytes out of an Unstructured this type needs to construct itself.

impl Clone for Literal

fn clone(&self) -> Literal

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Literal

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq<Literal> for Literal

fn eq(&self, other: &Literal) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
