Crate cap_rand

Capability-oriented random number generators

This corresponds to rand.

Capability-oriented APIs represent access to external resources as objects 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 objects.

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-oriented interface, avoid using rand::SeedableRng's from_entropy function on any of the types that implement that trait. rand: https://docs.rs/rand/current/rand/index.html [OsRng]: rngs/struct.OsRng.html [CapRng]: rngs/struct.CapRng.html

Traits

AsByteSliceMut	Trait for casting types to byte slices
