Enum Associativity

pub enum Associativity {
    Left,
    Right,
}

The associativity of a binary or unary operation.

Variants

Left

The binary / unary operation is left-associative.

For binary operations, this means a op b op c is evaluated as (a op b) op c. For unary operations, this means a op op is evaluated as (a op) op (the operators appear to the right of the operand).

Right

The binary / unary operation is right-associative.

For binary operations, this means a op b op c is evaluated as a op (b op c). For unary operations, this means op op a is evaluated as op (op a) (the operators appear to the left of the operand).

Trait Implementations

impl Clone for Associativity

fn clone(&self) -> Associativity

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Associativity

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

Formats the value using the given formatter.

impl PartialEq for Associativity

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

Tests for self and other values to be equal, and is used by ==.

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

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