Struct LiteralToken 

pub struct LiteralToken {
    pub kind: LiteralKind,
    /* private fields */
}

A literal spelling together with its lexical category and source span.

Fields

kind: LiteralKind

The literal’s lexical category.

Implementations

impl LiteralToken

pub fn from_span(kind: LiteralKind, span: Span) -> Self

Creates a literal token from its source span.

pub fn new(kind: LiteralKind, text: impl Into<Arc<str>>, span: Span) -> Self

Creates a literal token.

pub fn text(&self) -> &str

Returns the complete source spelling, including string delimiters.

Panics

Panics when sources cannot resolve this token’s span.
