Function grpcio_sys::grpc_init

pub unsafe extern "C" fn grpc_init()

Initialize the grpc library.

After it's called, a matching invocation to grpc_shutdown() is expected.

It is not safe to call any other grpc functions before calling this. (To avoid overhead, little checking is done, and some things may work. We do not warrant that they will continue to do so in future revisions of this library).
