Implementations§

source§

impl Lit

source

pub fn new(kind: LitKind, symbol: Symbol, suffix: Option<Symbol>) -> Lit

source

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.

source

pub fn from_token(token: &Token) -> Option<Lit>

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

source§

impl PartialEq<Lit> for Lit

source§

fn eq(&self, other: &Lit) -> bool

1.0.0 · source§

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

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.
