rand_core

Core traits and error types of the rand library, plus tools for implementing RNGs.

This crate is intended for use when implementing the core trait, RngCore; it defines the core traits to be implemented as well as several small functions to aid in their implementation and types required for error handling.

The main rand crate re-exports most items defined in this crate, along with tools to convert the integer samples generated by RngCore to many different applications (including sampling from restricted ranges, conversion to floating point, list permutations and secure initialisation of RNGs). Most users should prefer to use the main rand crate.
