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 is_comparison(&self) -> bool

source

pub fn is_assign_like(&self) -> bool

source

pub fn to_ast_binop(&self) -> Option<BinOpKind>

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)

Performs copy-assignment from source. Read more
source§

impl Debug for AssocOp

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

This method tests for self and other values to be equal, and is used by ==.
1.0.0 · source§

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

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.
