#[lang = "rem"]pub trait Rem<Rhs = Self> { type Output; fn rem(self, rhs: Rhs) -> Self::Output; }
The remainder operator %
.
Note that Rhs
is Self
by default, but this is not mandatory.
This example implements Rem
on a SplitSlice
object. After Rem
is implemented, one can use the %
operator to find out what the remaining elements of the slice would be after splitting it into equal slices of a given length.
use std::ops::Rem; #[derive(PartialEq, Debug)] struct SplitSlice<'a, T: 'a> { slice: &'a [T], } impl<'a, T> Rem<usize> for SplitSlice<'a, T> { type Output = Self; fn rem(self, modulus: usize) -> Self::Output { let len = self.slice.len(); let rem = len % modulus; let start = len - rem; SplitSlice {slice: &self.slice[start..]} } } // If we were to divide &[0, 1, 2, 3, 4, 5, 6, 7] into slices of size 3, // the remainder would be &[6, 7]. assert_eq!(SplitSlice { slice: &[0, 1, 2, 3, 4, 5, 6, 7] } % 3, SplitSlice { slice: &[6, 7] });
type Output
The resulting type after applying the %
operator.
impl Rem<f32> for f32
[src]
The remainder from the division of two floats.
The remainder has the same sign as the dividend and is computed as: x - (x / y).trunc() * y
.
let x: f32 = 50.50; let y: f32 = 8.125; let remainder = x - (x / y).trunc() * y; // The answer to both operations is 1.75 assert_eq!(x % y, remainder);
impl Rem<f64> for f64
[src]
The remainder from the division of two floats.
The remainder has the same sign as the dividend and is computed as: x - (x / y).trunc() * y
.
let x: f32 = 50.50; let y: f32 = 8.125; let remainder = x - (x / y).trunc() * y; // The answer to both operations is 1.75 assert_eq!(x % y, remainder);
