Struct nanorand::rand::chacha::ChaCha

source · [−]

pub struct ChaCha<const ROUNDS: u8> { /* private fields */ }

Expand description

An instance of the ChaCha random number generator. Seeded from the system entropy generator when available. This generator is theoretically cryptographically secure.
