Trait core::iter::Sum

pub trait Sum<A = Self>: Sized {
    // Required method
    fn sum<I: Iterator<Item = A>>(iter: I) -> Self;
}
Expand description

Trait to represent types that can be created by summing up an iterator.

This trait is used to implement Iterator::sum(). Types which implement this trait can be generated by using the sum() method on an iterator. Like FromIterator, this trait should rarely be called directly.

Required Methods§

source

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

Method which takes an iterator and generates Self from the elements by “summing up” the items.
