pub trait Rem<Rhs = Self> {
type Output;
// Required method
fn rem(self, rhs: Rhs) -> Self::Output;
}Expand description
The remainder operator %.
Note that Rhs is Self by default, but this is not mandatory.
Examples
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.

#[derive(PartialEq, Debug)]

fn rem(self, modulus: usize) -> Self::Output {
let len = self.slice.len();
let rem = len % modulus;
let start = len - rem;
Self {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].

source§impl Rem for f32
impl Rem for f32
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.
Examples
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);source§impl Rem for f64
