Detailed Description

Internal structure representing a single data log instance.

Holds all runtime state for one log, including the FatFs objects, the configured logging interval, the timestamp of the last write, and lifecycle flags.

This structure is opaque to the caller; it is accessed only through the DATALOG_HANDLE_ts pointer returned by datalog_init_handle.
