decky-loader/backend/decky_plugin.pyi

"""
This module exposes various constants and helpers useful for decky plugins.

* Plugin's settings and configurations should be stored under `DECKY_PLUGIN_SETTINGS_DIR`.
* Plugin's runtime data should be stored under `DECKY_PLUGIN_RUNTIME_DIR`.
* Plugin's persistent log files should be stored under `DECKY_PLUGIN_LOG_DIR`.

Avoid writing outside of `DECKY_HOME`, storing under the suggested paths is strongly recommended.

Some basic migration helpers are available: `migrate_any`, `migrate_settings`, `migrate_runtime`, `migrate_logs`.

A logging facility `logger` is available which writes to the recommended location.
