Detailed Description

Logs messages to files with date-based rotation and automatic deletion of old logs.

This logger writes logs to files organized by date. It supports asynchronous logging and manages old files based on a configurable retention period.

Key Features:

Date-based file rotation.
Automatic cleanup of old files.
Synchronous or asynchronous operation.

Definition at line 797 of file FileLogger.hpp.

◆ set_config()

void logit::FileLogger::set_config ( const Config & config )

inline

Updates executor-related configuration at runtime.

This call is blocking. If asynchronous logging is currently enabled, it waits until already accepted tasks are drained before changing async mode or executor ownership. Only async, use_dedicated_executor, queue_capacity, and queue_policy are applied. File/rotation/compression fields are ignored. For hot queue tuning without switching executor mode, use set_queue_config().

Definition at line 208 of file FileLogger.hpp.

◆ set_log_level()

inlineoverridevirtual

Sets the minimal log level for this logger.

Definition at line 366 of file FileLogger.hpp.

◆ set_queue_config()

bool logit::FileLogger::set_queue_config	(	std::size_t	queue_capacity,
		QueuePolicy	queue_policy )

inline

Updates queue_capacity and queue_policy at runtime without draining tasks.

Parameters

queue_capacity	New maximum queue size (0 = unlimited).
queue_policy	Overflow policy for the executor queue.

Returns: true if a dedicated executor was present and updated; false if the logger is shut down or uses the global executor.

Unlike set_config(), this method never blocks on task drain and never changes async mode or executor ownership. If no dedicated executor exists, only the stored config fields are updated for future reference.
