Building

You can build and install with cargo install --path ., which installs binaries in ~/.cargo/bin on Linux. 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.
