pub trait Sequence<T>: Iterator<Item = T>where
T: ConstZero,{
// Provided method
fn sum_next_n(&mut self, n: usize) -> T { ... }
}Expand description
A trait for mathematical sequences that can be iterated over.
Provided Methods§
Sourcefn sum_next_n(&mut self, n: usize) -> T
fn sum_next_n(&mut self, n: usize) -> T
Sum the next n elements of the sequence.
Advances the iterator by n elements.
If the iterator has fewer than n elements left, it sums as many as possible.
This should be used instead of .take(n).sum() because
some sequences have a more efficient implementation for summing elements.
§Arguments
n- The number of elements to sum.
§Returns
- The sum of the next
nelements in the sequence.
