余数运算符 %
。
请注意,默认情况下 Rhs
是 Self
,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] });
