Implementations§
source§impl AssocOp
impl AssocOp
sourcepub fn from_token(t: &Token) -> Option<AssocOp>
pub fn from_token(t: &Token) -> Option<AssocOp>
Creates a new AssocOP from a token
sourcepub fn from_ast_binop(op: BinOpKind) -> Self
pub fn from_ast_binop(op: BinOpKind) -> Self
Creates a new AssocOp from ast::BinOpKind.
sourcepub fn precedence(&self) -> usize
pub fn precedence(&self) -> usize
Gets the precedence of this operator
pub fn is_comparison(&self) -> bool
pub fn is_assign_like(&self) -> bool
pub fn to_ast_binop(&self) -> Option<BinOpKind>
sourcepub fn can_continue_expr_unambiguously(&self) -> bool
pub fn can_continue_expr_unambiguously(&self) -> bool
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.

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...)
attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
