A Rust RDMA library.
This library provides safe wrappers of the unsafe ibverbs interfaces, while preserving the original post-poll semantics.
Currently, there is no async support.
Beneath the interfaces exposed, every data structure maintains allocated ibv_* resources with an Arc if there are any.
As a result, such data structures can always be cloned.
Although this seems to introduce an unnecessary extra layer of indirection, it will also significantly relieve the programmer's
stress when they need to share the resources among threads.
