Expand description

A source of randomness.

Required Methods§

Source

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

🔬This is a nightly-only experimental API. (random #130703)

Fills bytes with random bytes.

Note that calling fill_bytes multiple times is not equivalent to calling fill_bytes once with a larger buffer. An Rng is allowed to return different bytes for those two cases. For instance, this allows an Rng to generate a word at a time and throw part of it away if not needed.

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
