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.

Methods

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.
