Struct BSD

pub struct BSD(/* private fields */);

Classic 32-bit 4.4BSD rand() number generator.

It got replaced in FreeBSD 5, still included in NetBSD and OpenBSD.

Implementations

impl BSD

pub fn new() -> Self

Constructs new BSD random generator.

Generator is implicitly initialized as if srand(1) had been invoked explicitly.

pub fn srand(seed: u32) -> Self

Seeds the algorithm with the seed parameter.

Repeatable sequence of rand() output may be obtained by calling srand() with the same seed.

pub fn rand(&mut self) -> i32

Computes a sequence of pseudo-random integers in the range 0 to RAND_MAX, inclusive.

pub fn rand_r(seed: &mut u32) -> i32

Computes a random number from provided seed.

Seed is updated and random number is returned.
