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
le sub-modules include a few small functions to assist
BlockRngCore trait and implementation helpers
Helper functions for implementing
Error type of random number generators
A random number generator that retrieves randomness from the operating system.
A marker trait used to indicate that an
implementation is supposed to be cryptographically secure.
The core of a random number generator.
A random number generator that can be explicitly seeded.
