Function to obtain a random integer.

get_bytes: rb_random_get_bytes_func

Function to obtain a series of random bytes. If your PRNG have a native method to yield arbitrary number of bytes use that to implement this. But in case you lack such things, you can do so by using rb_rand_bytes_int32

extern [`rb_random_get_int32_func`] your_get_int32_func;

void
your_get_byes_func([`rb_random_t`] *rng, void *buf, size_t len)
{
    [`rb_rand_bytes_int32`]your_get_int32_func, rng, buf, len);
}

get_real: rb_random_get_real_func

Function to obtain a random double. If your PRNG have a native method to yield a floating point random number use that to implement this. But in case you lack such things, you can do so by using rb_int_pair_to_real.

extern [`rb_random_get_int32_func`] your_get_int32_func;

void
your_get_real_func([`rb_random_t`] *rng, int excl)
{
    auto a = your_get_int32_func(rng);
    auto b = your_get_int32_func(rng);
    return [`rb_int_pair_to_real`]a, b, excl);

Trait Implementations

impl Clone for rb_random_interface_t

fn clone(&self) -> rb_random_interface_t

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for rb_random_interface_t

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

Formats the value using the given formatter.

impl PartialEq for rb_random_interface_t

fn eq(&self, other: &rb_random_interface_t) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
