A low-level binding crate for Rust that moves in lockstop with BoringSSL. BoringSSL explicitly does not have a stable ABI,
bssl-sys is the solution for preventing subtle-memory corruption bugs due to version skew.
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.
-DRUST_BINDINGS=<rust-triple> and ensure that you have
bindgen installed. The
rust-triple option should match the Rust target triple when building
From there, 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.
