Question

SingleQuote

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

OpenDelim(DelimToken)

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

CloseDelim(DelimToken)

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

Literal(Lit)

Ident(Name, bool)

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.

Lifetime(Name)

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.

Interpolated(Lrc<Nonterminal>)

DocComment(Name)

A doc comment.

Whitespace

Whitespace.

Comment

A comment.

Shebang(Name)

Unknown(Name)

A completely invalid token which should be skipped.

Eof

Methods

`impl TokenKind`[src]

`pub fn lit(kind: LitKind, symbol: Symbol, suffix: Option<Symbol>) -> TokenKind`[src]

`pub fn break_two_token_op(&self) -> Option<(TokenKind, TokenKind)>`[src]

`pub fn similar_tokens(&self) -> Option<Vec<TokenKind>>`[src]

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