Crate rand [−] [src]

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.

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.

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.

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.
