Expand description
Items related to randomness and random number generators. Also provides some high-level helper functions.
Helper functions include random_f32(), random_f64() and random_range(min, max).
Modules
- Utilities for random number generation
Structs
- Error type of random number generators
Traits
- A marker trait used to indicate that an
RngCore
orBlockRngCore
implementation is supposed to be cryptographically secure. - Types which may be filled with random data
- 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.
Functions
- Generates a random value using the thread-local random number generator.
- Generates and returns a random ascii character.
- A wrapper function around the
random
function that avoids the need for specifying a type in the case that it cannot be inferred. The primary purpose for this is to simplify the random API for new rust users. - A wrapper function around the
random
function that avoids the need for specifying a type in the case that it cannot be inferred. The primary purpose for this is to simplify the random API for new rust users. - A function for generating a random value within the given range.
- 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 theDefault
trait, makingThreadRng::default()
equivalent.
