Struct rustc_ast::ast::Lit[][src]

pub struct Lit {
    pub token: Lit,
    pub kind: LitKind,
    pub span: Span,
}
Expand description

An AST literal.

Fields

token: Lit

The original literal token as written in source code.

kind: 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

Implementations

Converts literal token into an AST literal.

Converts arbitrary token into an AST literal.

Keep this in sync with Token::can_begin_literal_or_bool excluding unary negation.

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).

Losslessly convert an AST literal into a token.

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.
