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.
