* Rename benches/mod.rs to benches/buffer.rs This naming makes more sense, especially if we add more benchmark files. Signed-off-by: Joe Richey <joerichey@google.com> * Rework benchmarks to make it easier to get assembly. This change: - Move the benchmarks from mod.rs to buffer.rs - Move the inner loop we benchmark into an `#[inline(never)]` function - Includes instructions for getting the ASM for a specific benchmark This should hopefully reduce the variance of these benchmarks and make it easier to figure out if we are emitting the assembly or IR we expect for a particular implementation.

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 1.36.0 or later.
