Variants

Start

No permutation generated yet.

Fields

k: usize

Buffered

Values from the iterator are not fully loaded yet so n is still unknown.

Fields

k: usize

min_n: usize

Loaded

All values from the iterator are known so n is known.

Fields

indices: Box<[usize]>

cycles: Box<[usize]>

End

No permutation left to generate.
