[−][src]Enum rustc_ap_syntax::token::TokenKind
Variants
BinOp(BinOpToken)
BinOpEq(BinOpToken)
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)
Lifetime(Name)
Interpolated(Lrc<Nonterminal>)
DocComment(Name)
A doc comment.
Whitespace.
A comment.
Shebang(Name)
Unknown(Name)
A completely invalid token which should be skipped.
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.
