Struct SessionPersistence 

pub struct SessionPersistence;

Session persistence utilities for managing session data in XDG directories.

This module provides functionality to save and load Last.fm session data using the XDG Base Directory Specification. Sessions are stored per-user in the format: ~/.local/share/lastfm-edit/users/{username}/session.json

Deprecated

Use SessionManager instead for more flexibility and customization.
