Trait std::iter::Product

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

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

This trait is used to implement the product() method on iterators. Types which implement the trait can be generated by the product() method. Like FromIterator this trait should rarely be called directly and instead interacted with through Iterator::product().

Required Methods

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

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