Trait core::iter::Product

pub trait Product<A = Self>: Sized {
    fn product<I: Iterator<Item = A>>(iter: I) -> Self;
}

This is supported on non-crate feature miri-test-libstd or test or doctest only.

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

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

Method which takes an iterator and generates Self from the elements by multiplying the items.
