Struct rustc_ast::token::Lit

pub struct Lit {
    pub kind: LitKind,
    pub symbol: Symbol,
    pub suffix: Option<Symbol>,
}

A literal token.

Fields

kind: LitKind

symbol: Symbol

suffix: Option<Symbol>

Implementations

impl Lit

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

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.

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

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

Trait Implementations

impl Clone for Lit

fn clone(&self) -> Lit

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Lit

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<__D: SpanDecoder> Decodable<__D> for Lit

fn decode(__decoder: &mut __D) -> Self

impl Display for Lit

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<__E: SpanEncoder> Encodable<__E> for Lit

fn encode(&self, __encoder: &mut __E)

impl<__CTX> HashStable<__CTX> for Lit

where __CTX: HashStableContext,

fn hash_stable(&self, __hcx: &mut __CTX, __hasher: &mut StableHasher)

impl PartialEq for Lit

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

Tests for self and other values to be equal, and is used by ==.

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

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.
