    fn sum<I>(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§

1.12.0 · source

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

Takes an iterator and generates Self from the elements by “summing up” the items.

Object Safety§

This trait is not object safe.
