Implementations

`impl AssocOp`[src]

`pub fn from_token(t: &Token) -> Option<AssocOp>`[src]

Creates a new AssocOP from a token

`pub fn from_ast_binop(op: BinOpKind) -> Self`[src]

Creates a new AssocOp from ast::BinOpKind.

`pub fn precedence(&self) -> usize`[src]

Gets the precedence of this operator

`pub fn fixity(&self) -> Fixity`[src]

Gets the fixity of this operator

`pub fn is_comparison(&self) -> bool`[src]

`pub fn is_assign_like(&self) -> bool`[src]

`pub fn to_ast_binop(&self) -> Option<BinOpKind>`[src]

`pub fn can_continue_expr_unambiguously(&self) -> bool`[src]

This operator could be used to follow a block unambiguously.

This is used for error recovery at the moment, providing a suggestion to wrap blocks with parentheses while having a high degree of confidence on the correctness of the suggestion.
