Trait SubAssign

pub trait SubAssign<Rhs = Self> {
    // Required method
    fn sub_assign(&mut self, rhs: Rhs);
}

core The subtraction assignment operator -=.

Re-exported from core::ops:: .

---

The subtraction assignment operator -=.

Examples

This example creates a Point struct that implements the SubAssign trait, and then demonstrates sub-assigning to a mutable Point.

use std::ops::SubAssign;

#[derive(Debug, Copy, Clone, PartialEq)]
struct Point {
    x: i32,
    y: i32,
}

impl SubAssign for Point {
    fn sub_assign(&mut self, other: Self) {
        *self = Self {
            x: self.x - other.x,
            y: self.y - other.y,
        };
    }
}

let mut point = Point { x: 3, y: 3 };
point -= Point { x: 2, y: 3 };
assert_eq!(point, Point {x: 1, y: 0});

Required Methods

fn sub_assign(&mut self, rhs: Rhs)

Performs the -= operation.

Example

let mut x: u32 = 12;
x -= 1;
assert_eq!(x, 11);

impl SubAssign<SignedDuration> for Date

Subtracts a signed duration of time from a date in place.

This uses checked arithmetic and panics on overflow. To handle overflow without panics, use Date::checked_sub.

impl SubAssign<SignedDuration> for DateTime

Subtracts a signed duration of time from a datetime in place.

This uses checked arithmetic and panics on overflow. To handle overflow without panics, use DateTime::checked_sub.

impl SubAssign<SignedDuration> for Time

Subtracts a signed duration of time in place. This uses wrapping arithmetic.

For checked arithmetic, see Time::checked_sub.

impl SubAssign<SignedDuration> for Timestamp

Subtracts a signed duration of time from a timestamp in place.

This uses checked arithmetic and panics on overflow. To handle overflow without panics, use Timestamp::checked_sub.

impl SubAssign<SignedDuration> for Zoned

Subtracts a signed duration of time from a zoned datetime in place.

This uses checked arithmetic and panics on overflow. To handle overflow without panics, use Zoned::checked_sub.

impl SubAssign<SignedDuration> for Offset

Subtracts a signed duration of time from an offset in place. This panics on overflow.

For checked arithmetic, see Offset::checked_sub.

impl SubAssign<Span> for Date

Subtracts a span of time from a date in place.

This uses checked arithmetic and panics on overflow. To handle overflow without panics, use Date::checked_sub.

impl SubAssign<Span> for DateTime

Subtracts a span of time from a datetime in place.

This uses checked arithmetic and panics on overflow. To handle overflow without panics, use DateTime::checked_sub.

impl SubAssign<Span> for Time

Subtracts a span of time in place. This uses wrapping arithmetic.

For checked arithmetic, see Time::checked_sub.

impl SubAssign<Span> for Timestamp

Subtracts a span of time from a timestamp in place.

This uses checked arithmetic and panics when it fails. To handle arithmetic without panics, use Timestamp::checked_sub. Note that the failure condition includes overflow and using a Span with non-zero units greater than hours.

impl SubAssign<Span> for Zoned

Subtracts a span of time from a zoned datetime in place.

This uses checked arithmetic and panics on overflow. To handle overflow without panics, use Zoned::checked_sub.
