Crate qubit_cas 

Typed compare-and-swap executor for synchronous and asynchronous workflows.

CasExecutor<T, E> binds the shared state type T and operation error type E. Each execution call introduces its own business output type R, so one executor configuration can serve multiple CAS operations over the same state.
