Dependencies

To leverage the barretenberg-sys crate, you'll need to install some global packages:

1. libomp

   Usually installable via brew install libomp or apt install libomp-dev.

2. pkg-config

   Usually installable via brew install pkg-config or apt install pkg-config.

3. lld

   Linker provided by Clang, but might need to be installed via apt install lld.

Usage

```rust pub fn pedersen() { let input = vec![0; 64]; barretenbergsys::blake2s::hashto_field(&input);

let f_zero = [0_u8; 32];
let mut f_one = [0_u8; 32];
f_one[31] = 1;
let got = barretenberg_sys::pedersen::compress_native(&f_zero, &f_one);
assert_eq!(
    "229fb88be21cec523e9223a21324f2e305aea8bff9cdbcb3d0c6bba384666ea1",
    hex::encode(got)
);

} ```
