1.0.0[−][src]Trait geng_core::prelude::Add
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 });
Associated Types
type Output
The resulting type after applying the +
operator.

impl<'a> Add<&'a str> for Cow<'a, str>
[src]
impl<'_> Add<&'_ str> for String
[src]
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;
impl Add<Duration> for NaiveDate
[src]
An addition of Duration
to NaiveDate
discards the fractional days,
rounding to the closest integral number of days towards Duration::zero()
.
Panics on underflow or overflow.
Use NaiveDate::checked_add_signed
to detect that.
Example

impl Add<Duration> for NaiveDateTime
[src]
An addition of Duration
to NaiveDateTime
yields another 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 on underflow or overflow.
Use NaiveDateTime::checked_add_signed
to detect that.
Example
use chrono::NaiveDate; use time::Duration; let from_ymd = NaiveDate::from_ymd; let d = from_ymd(2016, 7, 8); let hms = |h, m, s| d.and_hms(h, m, s); assert_eq!(hms(3, 5, 7) + Duration::zero(), hms(3, 5, 7)); assert_eq!(hms(3, 5, 7) + Duration::seconds(1), hms(3, 5, 8)); assert_eq!(hms(3, 5, 7) + Duration::seconds(-1), hms(3, 5, 6)); assert_eq!(hms(3, 5, 7) + Duration::seconds(3600 + 60), hms(4, 6, 7)); assert_eq!(hms(3, 5, 7) + Duration::seconds(86_400), from_ymd(2016, 7, 9).and_hms(3, 5, 7)); assert_eq!(hms(3, 5, 7) + Duration::days(365), from_ymd(2017, 7, 8).and_hms(3, 5, 7)); let hmsm = |h, m, s, milli| d.and_hms_milli(h, m, s, milli); assert_eq!(hmsm(3, 5, 7, 980) + Duration::milliseconds(450), hmsm(3, 5, 8, 430));
Leap seconds are handled, but the addition assumes that it is the only leap second happened.
let leap = hmsm(3, 5, 59, 1_300); assert_eq!(leap + Duration::zero(), hmsm(3, 5, 59, 1_300)); assert_eq!(leap + Duration::milliseconds(-500), hmsm(3, 5, 59, 800)); assert_eq!(leap + Duration::milliseconds(500), hmsm(3, 5, 59, 1_800)); assert_eq!(leap + Duration::milliseconds(800), hmsm(3, 6, 0, 100)); assert_eq!(leap + Duration::seconds(10), hmsm(3, 6, 9, 300)); assert_eq!(leap + Duration::seconds(-10), hmsm(3, 5, 50, 300)); assert_eq!(leap + Duration::days(1), from_ymd(2016, 7, 9).and_hms_milli(3, 5, 59, 300));

impl Add<Duration> for NaiveTime
[src]
An addition of Duration
to NaiveTime
wraps around and never overflows or underflows.
In particular the addition ignores integral number of days.
As a part of Chrono's leap second handling,
the addition assumes that there is no leap second ever,
except when the NaiveTime
itself represents a leap second
in which case the assumption becomes that there is exactly a single leap second ever.
Example
use chrono::NaiveTime; use time::Duration; let from_hmsm = NaiveTime::from_hms_milli; assert_eq!(from_hmsm(3, 5, 7, 0) + Duration::zero(), from_hmsm(3, 5, 7, 0)); assert_eq!(from_hmsm(3, 5, 7, 0) + Duration::seconds(1), from_hmsm(3, 5, 8, 0)); assert_eq!(from_hmsm(3, 5, 7, 0) + Duration::seconds(-1), from_hmsm(3, 5, 6, 0)); assert_eq!(from_hmsm(3, 5, 7, 0) + Duration::seconds(60 + 4), from_hmsm(3, 6, 11, 0)); assert_eq!(from_hmsm(3, 5, 7, 0) + Duration::seconds(7*60*60 - 6*60), from_hmsm(9, 59, 7, 0)); assert_eq!(from_hmsm(3, 5, 7, 0) + Duration::milliseconds(80), from_hmsm(3, 5, 7, 80)); assert_eq!(from_hmsm(3, 5, 7, 950) + Duration::milliseconds(280), from_hmsm(3, 5, 8, 230)); assert_eq!(from_hmsm(3, 5, 7, 950) + Duration::milliseconds(-980), from_hmsm(3, 5, 6, 970));
The addition wraps around.
assert_eq!(from_hmsm(3, 5, 7, 0) + Duration::seconds(22*60*60), from_hmsm(1, 5, 7, 0)); assert_eq!(from_hmsm(3, 5, 7, 0) + Duration::seconds(-8*60*60), from_hmsm(19, 5, 7, 0)); assert_eq!(from_hmsm(3, 5, 7, 0) + Duration::days(800), from_hmsm(3, 5, 7, 0));
Leap seconds are handled, but the addition assumes that it is the only leap second happened.
let leap = from_hmsm(3, 5, 59, 1_300); assert_eq!(leap + Duration::zero(), from_hmsm(3, 5, 59, 1_300)); assert_eq!(leap + Duration::milliseconds(-500), from_hmsm(3, 5, 59, 800)); assert_eq!(leap + Duration::milliseconds(500), from_hmsm(3, 5, 59, 1_800)); assert_eq!(leap + Duration::milliseconds(800), from_hmsm(3, 6, 0, 100)); assert_eq!(leap + Duration::seconds(10), from_hmsm(3, 6, 9, 300)); assert_eq!(leap + Duration::seconds(-10), from_hmsm(3, 5, 50, 300)); assert_eq!(leap + Duration::days(1), from_hmsm(3, 5, 59, 300));
