Trait for types implementing expand_message interface for hash_to_field

Required methods

fn expand_message<M, D>(msg: M, dst: D, len_in_bytes: usize) -> Vec<u8> where
    M: AsRef<[u8]>,
    D: AsRef<[u8]>, 

Expand the message with the domain separation tag into a random byte sequence

fn expand_message_in_place<M, D>(
    msg: M,
    dst: D,
    len_in_bytes: usize,
    out: &mut [u8]
) where
    M: AsRef<[u8]>,
    D: AsRef<[u8]>, 

Expand the message with the domain separation tag into a random byte sequence and store it in out. out must be big enough to hold all computational storage.
