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 whose spelling is already available through its span.

Panics

Panics when span has no source backing.

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 if this token’s invariant that its span is source-backed was violated.
