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.

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

Modules§

block
The BlockRngCore trait and implementation helpers
impls
Helper functions for implementing RngCore functions.
le
Little-Endian utilities

Structs§

OsError
Error type of OsRng
OsRng
An interface over the operating-system’s random data source
RngReadAdapter
Adapter that enables reading through a io::Read from a RngCore.
UnwrapErr
Wrapper around TryRngCore implementation which implements RngCore by panicking on potential errors.
UnwrapMut
Wrapper around TryRngCore implementation which implements RngCore by panicking on potential errors.
