pub trait Add<Rhs = Self> {
type Output;
// Required method
fn add(self, rhs: Rhs) -> Self::Output;
}
Expand description
The addition operator +
.
Note that Rhs
is Self
by default, but this is not mandatory. For
example, std::time::SystemTime
implements Add<Duration>
, which permits
operations of the form SystemTime = SystemTime + Duration
.
§Examples
§Add
able points
use std::ops::Add;
#[derive(Debug, Copy, Clone, PartialEq)]
struct Point {
x: i32,
y: i32,
}
impl Add for Point {
type Output = Self;
fn add(self, other: Self) -> Self {
Self {
x: self.x + other.x,
y: self.y + other.y,
}
}
}
assert_eq!(Point { x: 1, y: 0 } + Point { x: 2, y: 3 },
Point { x: 3, y: 3 });
§Implementing Add
with generics
Here is an example of the same Point
struct implementing the Add
trait
using generics.
use std::ops::Add;
#[derive(Debug, Copy, Clone, PartialEq)]
struct Point<T> {
x: T,
y: T,
}
// Notice that the implementation uses the associated type `Output`.
impl<T: Add<Output = T>> Add for Point<T> {
type Output = Self;
fn add(self, other: Self) -> Self::Output {
Self {
x: self.x + other.x,
y: self.y + other.y,
}
}
}
assert_eq!(Point { x: 1, y: 0 } + Point { x: 2, y: 3 },
Point { x: 3, y: 3 });

1.0.0 · Source§impl Add<&str> for String
Implements the +
operator for concatenating two strings.
impl Add<&str> for String
Implements the +
operator for concatenating two strings.
This consumes the String
on the left-hand side and re-uses its buffer (growing it if
necessary). This is done to avoid allocating a new String
and copying the entire contents on
every operation, which would lead to O(n^2) running time when building an n-byte string by
repeated concatenation.
The string on the right-hand side is only borrowed; its contents are copied into the returned
String
.
§Examples
Concatenating two String
s takes the first by value and borrows the second:
let a = String::from("hello");
let b = String::from(" world");
let c = a + &b;
// `a` is moved and can no longer be used here.
If you want to keep using the first String
, you can clone it and append to the clone instead:
let a = String::from("hello");
let b = String::from(" world");
let c = a.clone() + &b;
// `a` is still valid here.
Concatenating &str
slices can be done by converting the first to a String
:
let a = "hello";
let b = " world";
let c = a.to_string() + b;

The result will be clamped to valid days in the resulting month, see checked_add_months
for
details.
§Panics
Panics if:
- The resulting date would be out of range.
- The local time at the resulting date does not exist or is ambiguous, for example during a daylight saving time transition.
Strongly consider using DateTime<Tz>::checked_add_months
to get an Option
instead.

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.
