# Trait std::ops::RemAssign

1.8.0 · source ·

    pub trait RemAssign<Rhs = Self> {
        // Required method
        fn rem_assign(&mut self, rhs: Rhs);
    }

Expand description

The remainder assignment operator `%=`.

## Examples

    use std::ops::RemAssign;

    struct CookieJar { cookies: u32 }

    impl RemAssign<u32> for CookieJar {
        fn rem_assign(&mut self, piles: u32) {
            self.cookies %= piles;
        }
    }

    let mut jar = CookieJar { cookies: 31 };
    let piles = 4;

    println!("Splitting up {} cookies into {} even piles!", jar.cookies, piles);

    jar %= piles;

    println!("{} cookies remain in the cookie jar!", jar.cookies);
