[][src]Crate rand

Utilities for random number generation

This release is a compatibility wrapper around rand version 0.4. Please upgrade.

Modules

chacha

The ChaCha random number generator.

distributions

Sampling from random distributions.

isaac

The ISAAC random number generator.

os

Interfaces to the operating system provided random number generators.

read

A wrapper around any Read to treat it as an RNG.

reseeding

A wrapper around another RNG that reseeds it after it generates a certain number of random bytes.

Structs

AsciiGenerator

Iterator which will continuously generate random ascii characters.

ChaChaRng

A random number generator that uses the ChaCha20 algorithm [1].

Closed01

A wrapper for generating floating point numbers uniformly in the closed interval [0,1] (including both endpoints).

Generator

Iterator which will generate a stream of random items.

Isaac64Rng

A random number generator that uses ISAAC-64[1], the 64-bit variant of the ISAAC algorithm.

IsaacRng

A random number generator that uses the ISAAC algorithm[1].

Open01

A wrapper for generating floating point numbers uniformly in the open interval (0,1) (not including either endpoint).

OsRng

A random number generator that retrieves randomness straight from the operating system. Platform sources:

StdRng

The standard RNG. This is designed to be efficient on the current platform.

ThreadRng

The thread-local RNG.

XorShiftRng

An Xorshift[1] random number generator.

Traits

Rand

A type that can be randomly generated using an Rng.

Rng

A random number generator.

SeedableRng

A random number generator that can be explicitly seeded to produce the same stream of randomness multiple times.

Functions

random

Generates a random value using the thread-local random number generator.

sample [
Deprecated
]

DEPRECATED: use seq::sample_iter instead.

thread_rng

Retrieve the lazily-initialized thread-local random number generator, seeded by the system. Intended to be used in method chaining style, e.g. thread_rng().gen::<i32>().

weak_rng

Create a weak random number generator with a default algorithm and seed.
