# Trait core::iter::Product 1.12.0 [−] [src]

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

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

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

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)
