Implementations

source

impl AssocOp

source

pub fn from_token(t: &Token) -> Option<AssocOp>

Creates a new AssocOP from a token

source

pub fn from_ast_binop(op: BinOpKind) -> Self

Creates a new AssocOp from ast::BinOpKind.

source

pub fn precedence(&self) -> usize

Gets the precedence of this operator

source

pub fn fixity(&self) -> Fixity

Gets the fixity of this operator

source

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.

Trait Implementations

source

impl Clone for AssocOp

source

fn clone(&self) -> AssocOp

Returns a copy of the value. Read more

1.0.0 · source

fn clone_from(&mut self, source: &Self)

source

impl Debug for AssocOp

source

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter. Read more

source

impl PartialEq<AssocOp> for AssocOp

source

fn eq(&self, other: &AssocOp) -> bool

Performs the conversion.

Layout

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.
