Struct CallbackManager 

pub struct CallbackManager { /* private fields */ }

Manages all callback types for the logging system.

CallbackManager is thread-safe and allows multiple callbacks of each type to be registered and executed. All callbacks are stored in Arc<RwLock<>> for safe concurrent access.
