Type Alias Combinations 

pub type Combinations<I> = CombinationsGeneric<I, Vec<usize>>;

Iterator for Vec valued combinations returned by .combinations()

Aliased Type

pub struct Combinations<I> {
    indices: Vec<usize>,
    pool: LazyBuffer<I>,
    first: bool,
}

Fields

indices: Vec<usize>

pool: LazyBuffer<I>

first: bool

Implementations

impl<I: Iterator> Combinations<I>

pub(crate) fn reset(&mut self, k: usize)

Resets this Combinations back to an initial state for combinations of length k over the same pool data source. If k is larger than the current length of the data pool an attempt is made to prefill the pool so that it holds k elements.
