Struct InMemoryChangeLog 

Source 
pub struct InMemoryChangeLog { /* private fields */ }
Expand description

In-memory ChangeLog for tests and deployments without durable logging.

Stores entries in a HashMap. Clone-able so tests can hold a handle for direct inspection while the service owns a boxed copy.
