History

David Benjamin 690dcdf5c9 Make the old sk_* functions into full functions Due to b/290792019 and b/290785937, we need them to actually exist at the original symbols. For all of Rust's language-level safety benefits, the ecosystem seems determined to undo it with patterns that are even less safe than C. This is not great and the bugs need to be fixed, but do this for now to unblock the Android update.

bssl-sys

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.

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

Build boringssl with -DRUST_BINDINGS=<rust-triple> and ensure that you have bindgen installed. The rust-triple option should match the Rust target triple when building bssl-sys.

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.
