Struct BsdRandom 

pub struct BsdRandom { /* private fields */ }

BSD random() with the default 128-byte TYPE_3 state (deg=31, sep=3).

This is the classic Berkeley additive generator carried into glibc’s random() and therefore Linux glibc rand(). It is much better than the 15-bit System V LCG, but it is still a weak historical userspace PRNG.

Implementations

Trait Implementations

impl Clone for BsdRandom

fn clone(&self) -> BsdRandom

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for BsdRandom

fn fmt(&self, f: &mut Formatter<'_>) -> Result
