Struct syntax::ast::Lit

pub struct Lit {
    pub token: Lit,
    pub node: LitKind,
    pub span: Span,
}

An AST literal.

Fields

token: Lit

The original literal token as written in source code.

node: LitKind

The "semantic" representation of the literal lowered from the original tokens. Strings are unescaped, hexadecimal forms are eliminated, etc. FIXME: Remove this and only create the semantic representation during lowering to HIR.

span: Span

Methods

impl Lit

pub fn from_lit_kind(node: LitKind, span: Span) -> Lit

Attempts to recover an AST literal from semantic literal. This function is used when the original token doesn't exist (e.g. the literal is created by an AST-based macro) or unavailable (e.g. from HIR pretty-printing).
