[−][src]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.
