pub struct Lit {
pub kind: LitKind,
pub symbol: Symbol,
pub suffix: Option<Symbol>,
}
Expand description
A literal token.
Fields§
§kind: LitKind
§symbol: Symbol
§suffix: Option<Symbol>
Implementations§
source§impl Lit
impl Lit
pub fn new(kind: LitKind, symbol: Symbol, suffix: Option<Symbol>) -> Lit
sourcepub fn is_semantic_float(&self) -> bool
pub fn is_semantic_float(&self) -> bool
Returns true
if this is semantically a float literal. This includes
ones like 1f32
that have an Integer
kind but a float suffix.
sourcepub fn from_token(token: &Token) -> Option<Lit>
pub fn from_token(token: &Token) -> Option<Lit>
Keep this in sync with Token::can_begin_literal_maybe_minus
excluding unary negation.

attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
