Structs
A small-state, fast non-crypto PRNG
The standard RNG. The PRNG algorithm in
StdRng is chosen to be efficient
on the current platform, to be statistically strong and unpredictable
(meaning a cryptographically secure PRNG).A reference to the thread-local generator
Traits
A marker trait used to indicate that an
RngCore or BlockRngCore
implementation is supposed to be cryptographically secure.Types (distributions) that can be used to create a random instance of
T.Extension trait on iterators, providing random sampling methods.
An automatically-implemented extension trait on
RngCore providing high-level
generic methods for sampling values and other convenience methods.The core of a random number generator.
A random number generator that can be explicitly seeded.
Extension trait on slices, providing random mutation and sampling methods.
Functions
Generates a random value using the thread-local random number generator.
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>(), or cached locally, e.g.
let mut rng = thread_rng();. Invoked by the Default trait, making
ThreadRng::default() equivalent.
