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§

OsErroros_rng
Error type of OsRng
OsRngos_rng
An interface over the operating-system’s random data source
UnwrapErr
Wrapper around TryRngCore implementation which implements RngCore by panicking on potential errors.

Traits§

CryptoRng
A marker trait used to indicate that an RngCore implementation is supposed to be cryptographically secure.
RngCore
Implementation-level interface for RNGs
SeedableRng
A random number generator that can be explicitly seeded.
TryCryptoRng
A marker trait used to indicate that a TryRngCore implementation is supposed to be cryptographically secure.
TryRngCore
A potentially fallible variant of RngCore
