    fn cumsum<S>(self) -> Cumsum<Self, S>
    where
        Self: Sized,
        S: Add<Self::Item, Output = S>,

Extension trait for iterators: extra adaptors and methods for numerical iterators

Provided Methods

Important traits for Cumsum<I, S>

impl<I, S> Iterator for Cumsum<I, S> where
    I: Iterator,
    S: Add<I::Item, Output = S>,
    S: Zero + Clone,  type Item = S;

fn cumsum<S>(self) -> Cumsum<Self, S> where
    Self: Sized,
    S: Add<Self::Item, Output = S>,
    S: Zero, 

Return an iterator that produces the sequence of cumulative sums of the base iterator. The type of the sum is S.
