Struct FixedLengthRescueCommitment

Source 
pub struct FixedLengthRescueCommitment<F: RescueParameter, const INPUT_LEN: usize, const INPUT_LEN_PLUS_ONE: usize>(/* private fields */);
Expand description

Rescue-based Commitment instance for fixed-length input

§Note

the current ugly existence of INPUT_LEN_PLUS_ONE is due to unstable feature of using const generic in expression (namely can’t use INPUT_LEN + 1 in code).
