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