Struct Optimistic 

pub struct Optimistic;

Optimistic concurrency control - version checked on every write.

This is the default concurrency strategy for Repository. With this strategy, the repository tracks the stream version when loading an aggregate and verifies it hasn’t changed before appending new events. If the version changed (another writer appended events), the operation fails with a ConcurrencyConflict error.
