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.
