1.12.0[][src]Trait nom::lib::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.

Implementors

impl<T, U> Product<Option<U>> for Option<T> where
    T: Product<U>, 
[src]

fn product<I>(iter: I) -> Option<T> where
    I: Iterator<Item = Option<U>>, 
[src]

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.

impl<T, U, E> Product<Result<U, E>> for Result<T, E> where
    T: Product<U>, 
[src]

fn product<I>(iter: I) -> Result<T, E> where
    I: Iterator<Item = Result<U, E>>, 
[src]

Takes each element in the Iterator: if it is an Err, no further elements are taken, and the Err is returned. Should no Err occur, the product of all elements is returned.
