Trait gclient::ext::sp_core::sp_std::ops::Add

pub trait Add<Rhs = Self> {
    type Output;

    // Required method
    fn add(self, rhs: Rhs) -> Self::Output;
}

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

Addable 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 });

Required Associated Types

type Output

The resulting type after applying the + operator.

Required Methods

fn add(self, rhs: Rhs) -> Self::Output

Performs the + operation.

Example

assert_eq!(12 + 1, 13);

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 Strings 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;

type Output = String

impl Add<Duration> for SystemTime

impl Add<Duration> for NaiveDateTime

Add 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.

type Output = NaiveDateTime

impl Add<Duration> for NaiveTime

Add std::time::Duration to NaiveTime.

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

type Output = NaiveTime

impl Add<Duration> for Instant

type Output = Instant

impl Add<Months> for NaiveDate

Add Months to NaiveDate.

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. Consider using NaiveDate::checked_add_months to get an Option instead.

Example

use chrono::{Months, NaiveDate};

let from_ymd = |y, m, d| NaiveDate::from_ymd_opt(y, m, d).unwrap();

assert_eq!(from_ymd(2014, 1, 1) + Months::new(1), from_ymd(2014, 2, 1));

impl Add<Days> for NaiveDate

Add Days to NaiveDate.

Panics

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

impl Add<Days> for NaiveDateTime

Add Days to NaiveDateTime.

Panics

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

impl Add<FixedOffset> for NaiveDateTime

Add FixedOffset to NaiveDateTime.

Panics

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

type Output = NaiveDateTime

impl Add<FixedOffset> for NaiveTime

Add FixedOffset to NaiveTime.

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

type Output = NaiveTime

impl Add<TimeDelta> for NaiveDate

Add 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 Add<TimeDelta> for NaiveDateTime

Add 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.

Example

assert_eq!(hmsm(3, 5, 7, 980) + TimeDelta::try_milliseconds(450).unwrap(), hmsm(3, 5, 8, 430));
