boringssl-src

A crate for building boringssl.

This crate is intended to integrate with other build script to build boringssl.

1. To use the crate, just include it as build-dependency:

[build-dependencies]
boringssl-src = "0.2"

2. And then build it in build script:

let artifact = boringssl_src::Build::new().build();

3. If you just need to link it to your library, then let it setup directly:

artifacts.print_cargo_metadata();

If you want to make it available to existing build system, take CMake as an example, you can setup by using OPENSSL_ROOT_PATH:

let config = cmake::Config::new("native project");
config.define("OPENSSL_ROOT_DIR", format!("{}", boringssl_artifact.root_dir().display()));

Then cmake should be able to find the library by find_package(OpenSSL).

How and When is boringssl updated?

It's updated periodically. It for now serves as a build dependency for tikv/grpc-rs, so whenever grpc updates boringssl, this crate also updates the native dependency.
