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
The BlockRngCore
trait and implementation helpers
Helper functions for implementing RngCore
functions.
Little-Endian utilities
Structs
Error type of random number generators
getrandom
A random number generator that retrieves randomness from the operating system.
Traits
A marker trait used to indicate that an RngCore
or BlockRngCore
implementation is supposed to be cryptographically secure.
The core of a random number generator.
A random number generator that can be explicitly seeded.
