Expand description
Capability-based random number generators
This corresponds to rand.
Capability-based APIs represent access to external resources as values which can be passed around between different parts of a program.
Two notable features are the OsRng and CapRng types, which
wrap up access to the operating system entropy source in capability
values.
This crate uses the existing rand::SeedableRng trait rather than having
its own version, however while rand::SeedableRng is mostly just a pure
interface, it provides a from_entropy function which directly reads
from the operating system entropy source. To preserve the
capability-based interface, avoid using rand::SeedableRng’s
from_entropy function on any of the types that implement that trait; use
std_rng_from_entropy instead.
Modules
Generating random samples from probability distributions
Convenience re-export of common members.
Random number generators and adapters.
Sequence-related functionality
Structs
Instances of this AmbientAuthority type serve to indicate that the
[ambient_authority] function has been called, indicating that the user
has explicitly opted into using ambient authority.
Error type of random number generators
Traits
A marker trait used to indicate that an RngCore or BlockRngCore
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
Return an AmbientAuthority value, which allows use of functions that
include an AmbientAuthority argument.
Generates a random value using the thread-local random number generator.
Retrieve the standard random number generator, seeded by the system.
Retrieve the lazily-initialized thread-local random number generator, seeded by the system.
