Trait AddAssign

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

The addition assignment operator +=.

Examples

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

use std::ops::AddAssign;

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

impl AddAssign for Point {
    fn add_assign(&mut self, other: Self) {
        *self = Self {
            x: self.x + other.x,
            y: self.y + other.y,
        };
    }
}

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

Required Methods

fn add_assign(&mut self, rhs: Rhs)

Performs the += operation.

Example

let mut x: u32 = 12;
x += 1;
assert_eq!(x, 13);

impl AddAssign<TimeDelta> for NaiveDate

Add-assign of TimeDelta to NaiveDate.

This discards the fractional days in TimeDelta, rounding to the closest integral number of days towards TimeDelta::zero().

Panics

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

impl AddAssign<TimeDelta> for NaiveDateTime

Add-assign TimeDelta to 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_add_signed to get an Option instead.

impl AddAssign<TimeDelta> for NaiveTime

Add-assign TimeDelta to NaiveTime.

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

impl AddAssign<SignedDuration> for rustmax::jiff::civil::Date

Adds a signed duration of time to a date in place.

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

impl AddAssign<SignedDuration> for rustmax::jiff::civil::DateTime

Adds a signed duration of time to a datetime in place.

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

impl AddAssign<SignedDuration> for Time

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

For checked arithmetic, see Time::checked_add.

impl AddAssign<SignedDuration> for Timestamp

Adds a signed duration of time to a timestamp in place.

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

impl AddAssign<SignedDuration> for Zoned

Adds a signed duration of time to a zoned datetime in place.

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

impl AddAssign<SignedDuration> for Offset

Adds a signed duration of time to an offset in place. This panics on overflow.

For checked arithmetic, see Offset::checked_add.

impl AddAssign<Span> for rustmax::jiff::civil::Date

Adds a span of time to a date in place.

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

impl AddAssign<Span> for rustmax::jiff::civil::DateTime

Adds a span of time to a datetime in place.

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

impl AddAssign<Span> for Time

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

For checked arithmetic, see Time::checked_add.

impl AddAssign<Span> for Timestamp

Adds a span of time to a timestamp in place.

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

impl AddAssign<Span> for Zoned

Adds a span of time to a zoned datetime in place.

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

impl AddAssign<Span> for Offset

Adds a span of time to an offset in place. This panics on overflow.

For checked arithmetic, see Offset::checked_add.

impl AddAssign<Duration> for NaiveDateTime

Add-assign std::time::Duration to 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_add_signed to get an Option instead.

impl AddAssign<Duration> for NaiveTime

Add-assign std::time::Duration to NaiveTime.

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

impl AddAssign<Duration> for rustmax::jiff::civil::Date

Adds an unsigned duration of time to a date in place.

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

impl AddAssign<Duration> for rustmax::jiff::civil::DateTime

Adds an unsigned duration of time to a datetime in place.

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

impl AddAssign<Duration> for Time

Adds an unsigned duration of time in place. This uses wrapping arithmetic.

For checked arithmetic, see Time::checked_add.

impl AddAssign<Duration> for Timestamp

Adds an unsigned duration of time to a timestamp in place.

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

impl AddAssign<Duration> for Zoned

Adds an unsigned duration of time to a zoned datetime in place.

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

impl AddAssign<Duration> for Offset

Adds an unsigned duration of time to an offset in place. This panics on overflow.

For checked arithmetic, see Offset::checked_add.
