Struct IdentToken 

pub struct IdentToken { /* private fields */ }

An identifier spelling and its source span.

Implementations

impl IdentToken

pub fn from_span(span: Span) -> Self

Creates an identifier from its source span.

Panics

Panics when the span cannot resolve its source text.

pub fn new(text: impl Into<Arc<str>>, span: Span) -> Self

Creates an identifier token.

pub fn text(&self) -> &str

Returns the identifier spelling.

Panics

Panics when sources cannot resolve this token’s span.

pub fn source_qualifier(&self) -> Option<&Span>

Returns the Source$ prefix, including its $, when present.

pub fn index_qualifier(&self) -> Option<&Span>

Returns the $0 suffix, including its $, when present.
