Struct rand::rngs::EntropyRng

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.

Methods

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.
