Function umash_sys::umash_params_prepare

pub unsafe extern "C" fn umash_params_prepare(
    params: *mut umash_params
) -> bool

Converts a umash_params struct filled with random values into something usable by the UMASH functions below.

When it succeeds, this function is idempotent. Failure happens with probability < 2**-110 is params is filled with uniformly distributed random bits. That’s an astronomically unlikely event, and most likely signals an issue with the caller’s (pseudo-)random number generator.

@return false on failure, probably because the input was not random.
