[−][src]Struct rand::rngs::EntropyRng
use rngs::OsRng instead
An interface returning random data from external source(s), provided specifically for securely seeding algorithmic generators (PRNGs).
This is deprecated. It is suggested you use rngs::OsRng instead.
Methods
impl EntropyRng[src]
pub fn new() -> Self[src]
Create a new EntropyRng.
This method will do no system calls or other initialization routines,
those are done on first use. This is done to make new infallible,
and try_fill_bytes the only place to report errors.

fn fill<T: AsByteSliceMut + ?Sized>(&mut self, dest: &mut T)[src]
Fill dest entirely with random bytes (uniform value distribution), where dest is any type supporting [AsByteSliceMut], namely slices and arrays over primitive integer types (i8, i16, u32, etc.). Read more
fn try_fill<T: AsByteSliceMut + ?Sized>(
&mut self,
dest: &mut T
) -> Result<(), Error>[src]
&mut self,
dest: &mut T
) -> Result<(), Error>
Fill dest entirely with random bytes (uniform value distribution), where dest is any type supporting [AsByteSliceMut], namely slices and arrays over primitive integer types (i8, i16, u32, etc.). Read more
fn gen_bool(&mut self, p: f64) -> bool[src]
Return a bool with a probability p of being true. Read more
fn gen_ratio(&mut self, numerator: u32, denominator: u32) -> bool[src]
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. Read more
