Used by proc macros for representing lifetimes, not generated by lexer right now.

OpenDelim(DelimToken)

An opening delimiter (e.g., {).

Tuple Fields of OpenDelim

0: DelimToken
CloseDelim(DelimToken)

A closing delimiter (e.g., }).

Tuple Fields of CloseDelim

0: DelimToken
Literal(Lit)

Tuple Fields of Literal

0: Lit
Ident(Symbolbool)

Identifier token. Do not forget about NtIdent when you want to match on identifiers. It’s recommended to use Token::(ident,uninterpolate,uninterpolated_span) to treat regular and interpolated identifiers in the same way.

Tuple Fields of Ident

0: Symbol1: bool
Lifetime(Symbol)

Lifetime identifier token. Do not forget about NtLifetime when you want to match on lifetime identifiers. It’s recommended to use Token::(lifetime,uninterpolate,uninterpolated_span) to treat regular and interpolated lifetime identifiers in the same way.

Tuple Fields of Lifetime

0: Symbol
Interpolated(Lrc<Nonterminal>)

Tuple Fields of Interpolated

0: Lrc<Nonterminal>
DocComment(CommentKindAttrStyleSymbol)

A doc comment token. Symbol is the doc comment’s data excluding its “quotes” (///, /**, etc) similarly to symbols in string literal tokens.

Tuple Fields of DocComment

0: CommentKind1: AttrStyle2: Symbol
Eof

Implementations

Returns tokens that are likely to be typed accidentally instead of the current token. Enables better error recovery when the wrong token is found.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
