FFI bindings to Barretenberg

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.

  4. barretenberg (preferably at commit 500daf1ceb03771d2c01eaf1a86139a7ac1d814f)

    Needs to be built and installed following the instructions in the README. Note that barretenberg has its own dependencies that will need to be installed, such as cmake and ninja.

Usage

pub fn pedersen() {
    let input = vec![0; 64];
    barretenberg_sys::blake2s::hash_to_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)
    );
}
