Trait ItertoolsNum 

pub trait ItertoolsNum: Iterator {
    // Provided method
    fn cumsum<S>(self) -> Cumsum<Self, S> 
       where Self: Sized,
             S: Add<Self::Item, Output = S> + Zero { ... }
}

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

Provided Methods

fn cumsum<S>(self) -> Cumsum<Self, S>

where Self: Sized, S: Add<Self::Item, Output = S> + Zero,

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

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
