pub struct LogGuard { /* private fields */ }
Expand description
A guard that manages the lifecycle of the logging subsystem.
LogGuard
ensures the logging thread remains active while instances exist and properly
terminates when all guards are dropped. The system uses reference counting to track active
guards - when the last LogGuard
is dropped, the logging thread is joined to ensure all
pending log messages are written before the process terminates.
§Reference Counting
The logging system maintains a global atomic counter of active LogGuard
instances. This
ensures that:
- The logging thread remains active as long as at least one
LogGuard
exists. - All log messages are properly flushed when intermediate guards are dropped.
- The logging thread is cleanly terminated and joined when the last guard is dropped.
§Limits
The system supports a maximum of 255 concurrent LogGuard
instances.
