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.

[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

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

Structs

Error	Error type of random number generators
OsRng	A random number generator that retrieves randomness from from the operating system.

Traits

CryptoRng	A marker trait used to indicate that an [RngCore] or BlockRngCore implementation is supposed to be cryptographically secure.
RngCore	The core of a random number generator.
SeedableRng	A random number generator that can be explicitly seeded.
