Crate 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.

The le sub-module includes a few small functions to assist implementation of RngCore and SeedableRng.
