Building

The standard way to install b3sum is:

cargo install b3sum

On Linux for example, Cargo will put the compiled binary in ~/.cargo/bin. You might want to add that directory to your $PATH, or rustup might have done it for you when you installed Cargo.

If you want to install directly from this directory, you can run cargo install --path .. Or you can just build with cargo build --release, which puts the binary at ./target/release/b3sum.

AVX-512 support (via C FFI, with dynamic CPU feature detection) and multi-threading (via Rayon) are enabled by default. Note that the underlying blake3 crate does not enable those by default.
