Convenience re-export of common members
Like the standard library’s prelude, this module simplifies importing of common items. Unlike the standard prelude, the contents of this module must be imported manually:
use rand::prelude::*;Structs
- A small-state, fast non-crypto PRNG
 - The standard RNG. The PRNG algorithm in
StdRngis 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
RngCoreorBlockRngCoreimplementation 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
RngCoreproviding 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 theDefaulttrait, makingThreadRng::default()equivalent.
