Struct MountManager 

pub struct MountManager { /* private fields */ }

Manages Mounts: CRUD, lookup, and detection.

Mounts are persisted in the mounts SQLite table (same memory.db as memories and the legacy projects table).

Implementations

impl MountManager

pub fn new(db: Arc<MemoryDatabase>, event_bus: Option<EventBus>) -> Result<Self>

Create a new MountManager, loading existing Mounts from SQLite.

pub fn list_mounts(&self) -> Vec<Mount>

List all Mounts.

pub fn get_mount(&self, id: MountId) -> Option<Mount>

Get a Mount by ID.

pub fn get_mount_by_name(&self, name: &str) -> Option<Mount>

Get a Mount by name.

pub fn get_mounts_ordered(&self, ids: &[MountId]) -> Vec<Mount>

Get several Mounts by ID, preserving the request order. Missing IDs are skipped (they may have been deleted).

pub fn create_mount( &self, name: String, paths: Vec<PathBuf>, source: MountSource, ) -> Result<Mount>

Create a new Mount with the minimal RFC-025 input (name + paths).

pub fn update_enrichment( &self, id: MountId, auto_description: Option<String>, auto_meta: Option<MountMeta>, ) -> Result<Mount>

Update a Mount’s auto-enriched fields (agent-driven, RFC-025 Phase 3).

Only auto_description and auto_meta are writable here — name and paths are user-level and go through Self::rename / the web API.

pub fn rename(&self, id: MountId, new_name: String) -> Result<Mount>

Rename a Mount.

pub fn remove_mount(&self, id: MountId) -> Result<()>

Remove a Mount.

DB-first ordering (matches create_mount): if the DB delete fails the in-memory state is left untouched so the caller can retry and the Mount doesn’t silently reappear on restart.

If the Mount was AutoPromoted, its canonicalized root paths are recorded as dismissals (tombstones) so the background scanner does not immediately re-promote them (Promo-3). Manual mounts are removed without recording a tombstone (the user may still want auto-promotion for that root).

pub fn touch(&self, id: MountId)

Record that a Mount was used in a session.

pub fn detect(&self, message: &str) -> DetectionResult

Try to detect a Mount from a user message.

pub fn seed_auto_meta(&self, id: MountId) -> Result<()>

Seed auto_meta from the filesystem (RFC-025 §Auto-Meta).

Cheap heuristic detection on marker files. The agent refines this during enrichment. Idempotent — safe to call multiple times.

pub fn check_drift(&self, id: MountId) -> Result<bool>

Check marker-file drift and set enrichment_pending (RFC-025 §Enrichment).

Compares current marker mtimes against the stored snapshot. Returns true if any marker drifted (and the flag was set). Cheap: a handful of stat() calls.

pub fn check_all_drift(&self) -> Vec<MountId>

Check drift for all Mounts (Dream-time refresh, RFC-025).

Returns the IDs of Mounts whose content drifted.

pub fn promote_frequent_paths( &self, sessions: &[Session], config: &PromotionConfig, ) -> Vec<MountId>

RFC-025 Phase 5: scan session history and auto-create Mounts for paths that cross the frequency threshold.

Returns the IDs of newly-created Mounts (empty if none promoted). Safe to call repeatedly — paths already covered by an existing Mount are skipped, as are name collisions.
