Function number_encoding::combinadics::decode_mut

pub fn decode_mut(n: usize, k: usize, r: &mut [usize])

Writes the combination of a value to a slice.

The written combination can be encoded with encode to get back n.

let mut xs = vec![0; k];
decode_mut(n, k, &mut xs);
assert_eq!(encode(&xs), n);

See decode for a version that allocates a vector for the combination.

Panics

Panics in debug mode if n > 0 && k == 0.
