bssl-sys

A low-level binding crate for Rust that moves in lockstop with BoringSSL.

How it works

bssl-sys uses bindgen as part of the cmake build process to generate Rust compatibility shims for the targeted platform. It is important to generate it for the correct platform because bindgen uses LLVM information for alignment which varies depending on architecture.

To Use

  1. Build boringssl with -DRUST_BINDINGS=<rust-triple>, which should match the Rust target triple when building bssl-sys,
  2. install bindgen, and
  3. install cargo-deny.

After that, the bssl-sys crate can be built. By default, it looks for bindgen output and BoringSSL static libraries in the build directory. This can be reconfigured with BORINGSSL_BUILD_DIR environment variable. Note the environment variable is evaluated relative to rust/bssl-sys/src, so using an absolute path may be more convenient.
