Trait 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

Trait to represent types that can be created by multiplying elements of an iterator.

This trait is used to implement Iterator::product(). Types which implement this trait can be generated by using the product() method on an iterator. Like FromIterator, this trait should rarely be called directly.

Required Methods§

1.12.0 · source

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

Takes an iterator and generates Self from the elements by multiplying the items.

Object Safety§

This trait is not object safe.
