* Update to wasi 0.11 The main breaking change between v0.10 and v0.11 is that Error is removed in favour of Errno. Unfortunately we can't create an Errno from outside the wasi create so we're loosing some debug information for errors. I've opened an issue to add back such a constructor, see <https://github.com/bytecodealliance/wasi/issues/64>. * Use libc::strerror to get the error message on wasi Since wasi v0.11 doesn't (yet) provided a way to create Errno, see <https://github.com/bytecodealliance/wasi/issues/64>. * Remove libc dependency for WASI This does mean that we won't get an error message for the error type.
getrandom
A Rust library for retrieving random data from (operating) system source. It is
assumed that system always provides high-quality cryptographically secure random
data, ideally backed by hardware entropy sources. This crate derives its name
from Linux's getrandom function, but is cross platform, roughly supporting
the same set of platforms as Rust's std lib.
This is a low-level API. Most users should prefer using high-level random-number
library like rand.
Usage
Add this to your Cargo.toml:
[dependencies]
getrandom = "0.2"
Then invoke the getrandom function:
fn get_random_buf() -> Result<[u8; 32], getrandom::Error> {
let mut buf = [0u8; 32];
getrandom::getrandom(&mut buf)?;
Ok(buf)
}
For more information about supported targets, entropy sources, no_std targets,
crate features, WASM support and Custom RNGs see the
getrandom documentation and
getrandom::Error documentation.
Minimum Supported Rust Version
This crate requires Rust 1.34.0 or later.
