Crate coins_bip32::ecdsa::signature::rand_core

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.

Error is provided for error-handling. It is safe to use in no_std environments.

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

• Error
  Error type of random number generators
• OsRng
  A random number generator that retrieves randomness from the operating system.

Traits

• CryptoRng
  A marker trait used to indicate that an RngCore or BlockRngCore implementation is supposed to be cryptographically secure.
• CryptoRngCore
  An extension trait that is automatically implemented for any type implementing RngCore and CryptoRng.
• RngCore
  The core of a random number generator.
• SeedableRng
  A random number generator that can be explicitly seeded.
