std::ops::Rem - Rust
Description: API documentation for the Rust `Rem` trait in crate `std`.
Keywords: rust, rustlang, rust-lang, Rem

# Trait std::ops::Rem 1.0.0 [−] [src]

    #[lang = "rem"]
    pub trait Rem<RHS = Self> {
        type Output = Self;
        fn rem(self, rhs: RHS) -> Self::Output;
    }

The remainder operator `%`.

# 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.

    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 = SplitSlice<'a, T>;

        fn rem(self, modulus: usize) -> Self {
            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] });Run

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)
