Crate rand_core 

rand_core: core random number generation traits

This crate provides a collection of traits used by implementations of Random Number Generation (RNG) algorithms. Additionally, it includes helper utilities that assist with the implementation of these traits.

Note that the traits focus solely on the core RNG functionality. Most users should prefer the rand crate, which offers more advanced RNG capabilities built on these core traits, such as sampling from restricted ranges, generating floating-point numbers, list permutations, and more.

Modules

block

The Generator trait and BlockRng

utils

Utilties to aid trait implementations

Structs

UnwrapErr

Wrapper around TryRng implementation which implements Rng by panicking on potential errors.

Enums

Infallible

The error type for errors that can never happen.

Traits

CryptoRng

A marker trait for securely unpredictable infallible RNGs

Rng

Trait for infallible random number generators

RngCoreDeprecated

DEPRECATED: stub trait to print a deprecation warning and aid discovering that Rng is the replacement.

SeedableRng

A random number generator that can be explicitly seeded.

TryCryptoRng

A marker trait over TryRng for securely unpredictable RNGs

TryRng

Base trait for random number generators and random data sources

TryRngCoreDeprecated

DEPRECATED: stub trait to print a deprecation warning and aid discovering that TryRng is the replacement.
