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 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.

Traits

• CryptoRng
  A marker trait over RngCore for securely unpredictable RNGs
• RngCore
  Implementation-level interface for RNGs
• SeedableRng
  A random number generator that can be explicitly seeded.
• TryCryptoRng
  A marker trait over TryRngCore for securely unpredictable RNGs
• TryRngCore
