pub struct CapRng { /* private fields */ }
Expand description
The type returned by thread_rng
, essentially just a reference to a
PRNG in memory.
This corresponds to rand::rngs::ThreadRng
, except that it isn’t
tied to thread-local memory.
Implementations
sourceimpl CapRng
impl CapRng
sourcepub fn default(ambient_authority: AmbientAuthority) -> Self
pub fn default(ambient_authority: AmbientAuthority) -> Self
A convenience alias for calling thread_rng
.
Ambient Authority
This function makes use of ambient authority to access the platform entropy source.

fn gen_ratio(&mut self, numerator: u32, denominator: u32) -> bool
Return a bool with a probability of
numerator/denominator
of being
true. I.e. gen_ratio(2, 3)
has chance of 2 in 3, or about 67%, of
returning true. If numerator == denominator
, then the returned value
is guaranteed to be true
. If numerator == 0
, then the returned
value is guaranteed to be false
