The cap-rand
crate provides a capability-based interface to random number
generators via the rand
crate.
lib.rs
:
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.
