Random number generation traits
This crate is mainly of interest to crates publishing implementations of
RngCore
. Other users are encouraged to use the rand
crate instead
which re-exports the main traits and error types.
RngCore
is the core trait implemented by algorithmic pseudo-random number
generators and external random-number sources.
SeedableRng
is an extension trait for construction from fixed seeds and
other random number generators.
The impls
and le
sub-modules include a few small functions to assist
implementation of RngCore
.
Modules§
- block
- The
BlockRngCore
trait and implementation helpers - impls
- Helper functions for implementing
RngCore
functions. - le
- Little-Endian utilities
Structs§
- OsError
os_rng
- Error type of
OsRng
- OsRng
os_rng
- An interface over the operating-system’s random data source
- Unwrap
Err - Wrapper around
TryRngCore
implementation which implementsRngCore
by panicking on potential errors.
Traits§
- Crypto
Rng - A marker trait used to indicate that an
RngCore
implementation is supposed to be cryptographically secure. - RngCore
- Implementation-level interface for RNGs
- Seedable
Rng - A random number generator that can be explicitly seeded.
- TryCrypto
Rng - A marker trait used to indicate that a
TryRngCore
implementation is supposed to be cryptographically secure. - TryRng
Core - A potentially fallible variant of
RngCore
