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

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

Implementations on Foreign Types

Takes each element in the Iterator: if it is a None, no further elements are taken, and the None is returned. Should no None occur, the product of all elements is returned.
