"""firebird-driver - Driver Hooks
This module defines specific hook points (events) within the firebird-driver
lifecycle where custom functions can be registered and executed. These hooks
allow for extending or modifying driver behavior, logging, or monitoring.
Hooks are registered using `firebird.driver.add_hook()` or the `firebird.base.hooks.hook_manager`.
The specific signature required for each hook function and the context in which
it's called are documented within the driver methods that trigger these hooks
(primarily in `firebird.driver.core`).
