Methods

impl Ident

pub const fn new(name: Symbol, span: Span) -> Ident

pub const fn with_empty_ctxt(name: Symbol) -> Ident

pub fn from_interned_str(string: InternedString) -> Ident

Maps an interned string to an identifier with an empty syntax context.

pub fn from_str(string: &str) -> Ident

Maps a string to an identifier with an empty syntax context.

pub fn with_span_pos(self, span: Span) -> Ident

Replace lo and hi with those from span, but keep hygiene context.

pub fn without_first_quote(self) -> Ident

pub fn modern(self) -> Ident

"Normalize" ident for use in comparisons using "item hygiene". Identifiers with same string value become same if they came from the same "modern" macro (e.g. macro item, but not macro_rules item) and stay different if they came from different "modern" macros. Technically, this operation strips all non-opaque marks from ident's syntactic context.

pub fn gensym(self) -> Ident

pub fn as_str(self) -> LocalInternedString

pub fn as_interned_str(self) -> InternedString

impl Ident

pub fn is_special(self) -> bool

pub fn is_used_keyword(self) -> bool

Returns true if the token is a keyword used in the language.

pub fn is_unused_keyword(self) -> bool

Returns true if the token is a keyword reserved for possible future use.

pub fn is_reserved(self) -> bool

Returns true if the token is either a special identifier or a keyword.

pub fn is_path_segment_keyword(self) -> bool

A keyword or reserved identifier that can be used as a path segment.

pub fn is_raw_guess(self) -> bool
