-- | Low-level safe interface to gRPC. By "safe", we mean:
-- 1. all gRPC objects are guaranteed to be cleaned up correctly.
-- 2. all functions are thread-safe.
-- 3. all functions leave gRPC in a consistent, safe state.
-- These guarantees only apply to the functions exported by this module,
-- and not to helper functions in submodules that aren't exported here.
