Crate coins_bip32::ecdsa::signature::rand_core

Random number generation traits

This crate is mainly of interest to crates publishing implementations of RngCore. Other users are encouraged to use the rand crate instead which re-exports the main traits and error types.

RngCore is the core trait implemented by algorithmic pseudo-random number generators and external random-number sources.

SeedableRng is an extension trait for construction from fixed seeds and other random number generators.

Error is provided for error-handling. It is safe to use in no_std environments.

The impls and le sub-modules include a few small functions to assist implementation of RngCore.

Modules

block

Traits

CryptoRng

A marker trait used to indicate that an RngCore or BlockRngCore implementation is supposed to be cryptographically secure.

RngCore

The core of a random number generator.

SeedableRng

A random number generator that can be explicitly seeded.
