Struct SessionBackedMinor 

pub struct SessionBackedMinor {
    pub active: Arc<dyn Fn(BufferId) -> bool + Send + Sync>,
    pub mode_id: ModeId,
}

A minor mode whose active/inactive state is driven by a predicate reading a shared, mode-owned session service — reconciled on the active buffer each sync_keymap_overlays cycle. Modes contribute these at boot so the generic overlay-sync carries no subsystem-specific knowledge: active-snippet-mode keys off the shared SnippetSession (lattice_snippet::snippet_active_predicate). See feedback_mode_owns_its_surface.

Fields

active: Arc<dyn Fn(BufferId) -> bool + Send + Sync>

true ⇒ the mode should be active on the given buffer. SN.3e: the predicate is buffer-scoped so a session live in one buffer never activates the mode in another; sync_keymap_overlays passes the buffer it is reconciling.

mode_id: ModeId

The minor mode toggled by active.
