Trait SubAssign

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

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<Duration> for std::time::Instant

impl SubAssign<Duration> for SystemTime

impl SubAssign<Duration> for NaiveDateTime

Subtract-assign std::time::Duration from NaiveDateTime.

As a part of Chrono’s [leap second handling], the addition assumes that there is no leap second ever, except when the NaiveDateTime itself represents a leap second in which case the assumption becomes that there is exactly a single leap second ever.

Panics

Panics if the resulting date would be out of range. Consider using NaiveDateTime::checked_sub_signed to get an Option instead.

impl SubAssign<Duration> for NaiveTime

Subtract-assign std::time::Duration from NaiveTime.

This wraps around and never overflows or underflows. In particular the subtraction ignores integral number of days.

impl SubAssign<TimeDelta> for NaiveDate

Subtract-assign TimeDelta from NaiveDate.

This discards the fractional days in TimeDelta, rounding to the closest integral number of days towards TimeDelta::zero(). It is the same as the addition with a negated TimeDelta.

Panics

Panics if the resulting date would be out of range. Consider using NaiveDate::checked_sub_signed to get an Option instead.
