pub struct EntropyRng { /* fields omitted */ }

👎 Deprecated since 0.7.0:

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.

Implementations

impl EntropyRng

pub fn new() -> Self

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.

Trait Implementations

impl Debug for EntropyRng

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

Formats the value using the given formatter.

impl Default for EntropyRng

fn default() -> Self

Returns the “default value” for a type.

impl RngCore for EntropyRng

fn next_u32(&mut self) -> u32

Return the next random u32.

fn next_u64(&mut self) -> u64

Return the next random u64.

fn fill_bytes(&mut self, dest: &mut [u8])

Fill dest with random data.

fn try_fill_bytes(&mut self, dest: &mut [u8]) -> Result<(), Error>

Fill dest entirely with random data.
