Struct LitNumber

#[non_exhaustive]
pub struct LitNumber {
    pub span: Span,
    pub source: NumberSource,
}

A number literal.

• 42.
• 4.2e10.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

span: Span

The span corresponding to the literal.

source: NumberSource

The source of the number.

Trait Implementations

impl Clone for LitNumber

fn clone(&self) -> LitNumber

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for LitNumber

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

Formats the value using the given formatter.

impl OptionSpanned for LitNumber

fn option_span(&self) -> Option<Span>

Get the optional span of the type.

impl Parse for LitNumber

fn parse(parser: &mut Parser<'_>) -> Result<Self, Error>

Parse the current item from the parser.

impl PartialEq for LitNumber

fn eq(&self, other: &LitNumber) -> 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.

impl Spanned for LitNumber

fn span(&self) -> Span

Get the span of the type.

impl ToTokens for LitNumber

fn to_tokens( &self, _: &mut MacroContext<'_, '_, '_>, stream: &mut TokenStream, ) -> Result<()>

Turn the current item into tokens.

impl TryClone for LitNumber

fn try_clone(&self) -> Result<Self>

Try to clone the current value, raising an allocation error if it’s unsuccessful.

fn try_clone_from(&mut self, source: &Self) -> Result<(), Error>

Performs copy-assignment from source.
