Detailed Documentation
~~~~~~~~~~~~~~~~~~~~~~

Structure that is stored in the tree of log nodes instead of :ref:`log_msg <doxid-structlog__msg>` structure for each regular log message. It is used to reduce memory consumption: full log message is loaded to memory from file only when we need to process it, and memory is released as soon as we end with it.
