An assignment operator assigns a value to its left operand based on the value of its right operand.

The simple assignment operator is equal (=), which assigns the value of its right operand to its left operand. That is, x = y assigns the value of y to x.

There are also compound assignment operators that are shorthand for the operations

Variants

Assign

The assignment operator assigns the value of the right operand to the left operand.

Syntax: x = y

More information:

• ECMAScript reference
• MDN documentation

Add

The addition assignment operator adds the value of the right operand to a variable and assigns the result to the variable.

Syntax: x += y

The types of the two operands determine the behavior of the addition assignment operator. Addition or concatenation is possible.

More information:

• ECMAScript reference
• MDN documentation

Sub

The subtraction assignment operator subtracts the value of the right operand from a variable and assigns the result to the variable.

Syntax: x -= y

More information:

• ECMAScript reference
• MDN documentation

Mul

The multiplication assignment operator multiplies a variable by the value of the right operand and assigns the result to the variable.

Syntax: x *= y

More information:

• ECMAScript reference
• MDN documentation

Div

The division assignment operator divides a variable by the value of the right operand and assigns the result to the variable.

Syntax: x /= y

More information:

• ECMAScript reference
• MDN documentation

Mod

The remainder assignment operator divides a variable by the value of the right operand and assigns the remainder to the variable.

Syntax: x %= y

More information:

• ECMAScript reference
• MDN documentation

Exp

The exponentiation assignment operator raises the value of a variable to the power of the right operand.

Syntax: x ** y

More information:

• ECMAScript reference
• MDN documentation

And

The bitwise AND assignment operator uses the binary representation of both operands, does a bitwise AND operation on them and assigns the result to the variable.

Syntax: x &= y

More information:

• ECMAScript reference
• MDN documentation

Or

The bitwise OR assignment operator uses the binary representation of both operands, does a bitwise OR operation on them and assigns the result to the variable.

Syntax: x |= y

More information:

• ECMAScript reference
• MDN documentation

Xor

The bitwise XOR assignment operator uses the binary representation of both operands, does a bitwise XOR operation on them and assigns the result to the variable.

Syntax: x ^= y

More information:

• ECMAScript reference
• MDN documentation

Shl

The left shift assignment operator moves the specified amount of bits to the left and assigns the result to the variable.

Syntax: x <<= y

More information:

• ECMAScript reference
• MDN documentation

Shr

The right shift assignment operator moves the specified amount of bits to the right and assigns the result to the variable.

Syntax: x >>= y

More information:

• ECMAScript reference
• MDN documentation

Ushr

The unsigned right shift assignment operator moves the specified amount of bits to the right and assigns the result to the variable.

Syntax: x >>>= y

More information:

• ECMAScript reference
• MDN documentation

BoolAnd

The logical and assignment operator only assigns if the target variable is truthy.

Syntax: x &&= y

More information:

• ECMAScript reference
• MDN documentation

BoolOr

The logical or assignment operator only assigns if the target variable is falsy.

Syntax: x ||= y

More information:

• ECMAScript reference
• MDN documentation

Coalesce

The logical nullish assignment operator only assigns if the target variable is nullish (null or undefined).

Syntax: x ??= y

More information:

• ECMAScript reference
• MDN documentation

Trait Implementations

impl<'arbitrary> Arbitrary<'arbitrary> for AssignOp

fn arbitrary(u: &mut Unstructured<'arbitrary>) -> Result<Self>

Generate an arbitrary value of Self from the given unstructured data.

fn arbitrary_take_rest(u: Unstructured<'arbitrary>) -> Result<Self>

Generate an arbitrary value of Self from the entirety of the given unstructured data.

fn size_hint(depth: usize) -> (usize, Option<usize>)

Get a size hint for how many bytes out of an Unstructured this type needs to construct itself.

fn try_size_hint( depth: usize, ) -> Result<(usize, Option<usize>), MaxRecursionReached>

Get a size hint for how many bytes out of an Unstructured this type needs to construct itself.

impl Clone for AssignOp

fn clone(&self) -> AssignOp

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AssignOp

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for AssignOp

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for AssignOp

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

impl PartialEq for AssignOp

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

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<Punctuator> for AssignOp

type Error = String

The type returned in the event of a conversion error.

fn try_from(punct: Punctuator) -> Result<Self, Self::Error>

Performs the conversion.
