pub struct Ident {
    pub span: Span,
    /* private fields */
}

Owned equivalent of Ident, with the same API and serialized form.

Fields

span: Span

Source range of the identifier token; includes the $ of a variable name.

Implementations

impl Ident

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

Construct an identifier from a non-empty name.

pub const fn error(span: Span) -> Self

Placeholder for “no identifier was parsed” at span.

pub fn as_str(&self) -> Option<&str>

Returns Some(s) for a real identifier, None for the error state.

pub fn is_error(&self) -> bool

Returns true if this identifier was synthesised during error recovery.

pub fn or_error(&self) -> &str

Returns the inner string, or "<error>" for the error state.
