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

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

余数运算符 %

请注意,默认情况下 RhsSelf,但这不是强制性的。

Examples

本示例在 SplitSlice 对象上实现 Rem。 实现 Rem 后,可以使用 % 运算符将其拆分为给定长度的相等切片后,找出切片的其余元素。

use std::ops::Rem;

#[derive(PartialEq, Debug)]
struct SplitSlice<'a, T> {
    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;
        Self {slice: &self.slice[start..]}
    }
}

// 如果将 &[0,1、2、3、4、5、6、7] 分成大小为 3 的切片,则其余部分将为 &[6,7]。
assert_eq!(SplitSlice { slice: &[0, 1, 2, 3, 4, 5, 6, 7] } % 3,
           SplitSlice { slice: &[6, 7] });
