Enum BinOp 

pub enum BinOp {
    Add,
    Sub,
    Mul,
    Div,
    Mod,
    Eq,
    Neq,
    Lt,
    Le,
    Gt,
    Ge,
    And,
    Or,
}

A binary operator. Arithmetic operands and result are Number; comparison operands share a type and the result is Bool; logical operands and result are Bool (short-circuit). Deliberately small (Principle 9): one canonical operator per operation.

Variants

Add

Sub

Mul

Div

Mod

Signed remainder (a % b); arithmetic, both operands Number.

Eq

Neq

a != b — the negation of Eq, same operand rule.

Lt

Le

a <= b.

Gt

a > b.

Ge

a >= b.

And

Short-circuit boolean conjunction; both operands Bool.

Or

Short-circuit boolean disjunction; both operands Bool.

Implementations

impl BinOp

pub fn is_comparison(self) -> bool

Comparisons yield Bool over two same-typed operands.

pub fn is_logical(self) -> bool

Logical operators take and yield Bool and short-circuit.

pub fn symbol(self) -> &'static str

The Section 5 infix symbol.

Trait Implementations

impl Clone for BinOp

fn clone(&self) -> BinOp

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BinOp

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for BinOp

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for BinOp

fn eq(&self, other: &BinOp) -> 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.

impl Serialize for BinOp

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
