Trait std::iter::Product

1.12.0 · source ·
pub trait Product<A = Self>: Sized {
    // Required method
    fn product<I>(iter: I) -> Self
       where I: Iterator<Item = A>;
}
Expand description

一个表示可以通过将迭代器的元素相乘来创建类型的 trait。

这个 trait 用于实现 Iterator::product()。 可以通过在迭代器上使用 product() 方法生成实现此 trait 的类型。

FromIterator 一样,这个 trait 应该很少被直接调用。

Required Methods§

source

fn product<I>(iter: I) -> Selfwhere I: Iterator<Item = A>,

该方法采用迭代器并通过乘以项从元素生成 Self
