Required Methods

fn get_insecure_random_bytes(&mut self, len: u64) -> Result<Vec<u8>>

Return len insecure pseudo-random bytes.

This function is not cryptographically secure. Do not use it for anything related to security.

There are no requirements on the values of the returned bytes, however implementations are encouraged to return evenly distributed values with a long period.

fn get_insecure_random_u64(&mut self) -> Result<u64>

Return an insecure pseudo-random u64 value.

This function returns the same type of pseudo-random data as get-insecure-random-bytes, represented as a u64.
