Struct Ident

#[non_exhaustive]
pub struct Ident {
    pub span: Span,
    pub source: LitSource,
}

An identifier, like foo or Hello.

Constructing identifiers

Inside of a macro context, identifiers have to be constructed through MacroContext::ident.

use rune::ast;
use rune::macros;

macros::test(|cx| {
    let lit = cx.ident("foo")?;
    assert!(matches!(lit, ast::Ident { .. }));
    Ok(())
})?;

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 of the identifier.

source: LitSource

The kind of the identifier.

Trait Implementations

impl Clone for Ident

fn clone(&self) -> Ident

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Ident

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

Formats the value using the given formatter.

impl OptionSpanned for Ident

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

Get the optional span of the type.

impl Parse for Ident

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

Parse the current item from the parser.

impl PartialEq for Ident

fn eq(&self, other: &Ident) -> 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 Peek for Ident

fn peek(p: &mut Peeker<'_>) -> bool

Peek the parser for the given token.

impl Spanned for Ident

fn span(&self) -> Span

Get the span of the type.

impl ToTokens for Ident

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

Turn the current item into tokens.

impl TryClone for Ident

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.

impl Copy for Ident

impl Eq for Ident

impl StructuralPartialEq for Ident
