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
  • A random number generator that retrieves randomness from the operating system.
