Struct SessionModelManager 

pub struct SessionModelManager { /* private fields */ }

Manages the session-model overlay lifecycle.

Tracks original config values so we can:

• Restore before save_config() to prevent leaking overlay to settings.json
• Revert on /session-model clear or /clear

Implementations

impl SessionModelManager

pub fn new() -> Self

Create a new manager with no active overlay.

pub fn is_active(&self) -> bool

Whether a session-model overlay is currently active.

pub fn apply<G, S>( &mut self, overlay: &SessionOverlay, get_config_value: G, set_config_value: S, )

where G: Fn(&str) -> Option<String>, S: Fn(&str, &str),

Apply an overlay, recording the original values from the provided config getter.

The get_config_value closure retrieves the current config value for a given key. The set_config_value closure applies the override.

pub fn restore<S>(&mut self, set_config_value: S)

where S: Fn(&str, &str),

Restore original config values, removing the overlay.

The set_config_value closure applies each restored value.

pub fn get_overlay(&self) -> Option<&SessionOverlay>

Return the current overlay dict (for persistence).
