Struct SyncMapping 

pub struct SyncMapping { /* private fields */ }

Mapping between Heddle StateIds and Git commit object IDs.

Implementations

impl SyncMapping

pub fn new() -> Self

Create a new empty mapping.

pub fn insert(&mut self, state_id: StateId, git_oid: ObjectId)

Insert a mapping.

pub fn insert_checked( &mut self, state_id: StateId, git_oid: ObjectId, ) -> GitProjectionResult<()>

Insert a mapping and detect conflicts.

pub fn get_git(&self, state_id: &StateId) -> Option<ObjectId>

Get Git object id for a Heddle StateId.

pub fn get_heddle(&self, git_oid: ObjectId) -> Option<StateId>

Get Heddle StateId for a Git object id.

pub fn has_heddle(&self, state_id: &StateId) -> bool

Check if a mapping exists for a StateId.

pub fn remove(&mut self, state_id: &StateId) -> Option<ObjectId>

Drop the mapping for state_id, clearing both directions. Returns the Git OID that was mapped, if any.

The export visibility purge calls this to remove a state whose effective tier is no longer served by the export audience. Without it, a stale StateId→OID mapping (minted while the state was public, kept alive by the notes/cache rebuild on the next export) makes the frontier walk and the tag/note sync treat a now-embargoed commit as served — leaking it via refs/heads/<thread> or a tag.

pub fn has_git(&self, git_oid: ObjectId) -> bool

Check if a mapping exists for a Git object id.

pub fn iter(&self) -> impl Iterator<Item = (&StateId, &ObjectId)>

Iterate over mappings.

pub fn is_empty(&self) -> bool

Whether the in-memory mapping holds no StateId → git OID entries. The checkout-materialization path (#568 P1) uses this to decide whether it must hydrate the mapping from disk (a standalone projection checkout) or trust the mapping export just built in memory (a checkpoint/push).

pub fn retain_git_objects(&mut self, repo: &SleyRepository)

pub fn retain_git_object_set(&mut self, reachable: &HashSet<ObjectId>) -> usize
