raw_rand
This section is a work in progress.
Examples:
from kybra import Async, blob, CallResult, match, update
from kybra.canisters.management import management_canister
@update
def get_randomness_directly() -> Async[blob]:
randomness_result: CallResult[blob] = yield management_canister.raw_rand()
return match(randomness_result, {"Ok": lambda ok: ok, "Err": lambda err: err})
