Struct ExportStats 

pub struct ExportStats {
    pub states_exported: usize,
    pub commits_total: usize,
    pub threads_synced: usize,
    pub markers_synced: usize,
    pub branches: Vec<ExportedRef>,
    pub tags: Vec<ExportedRef>,
    pub failed_refs: Vec<(String, FailedRefExportReason)>,
}

Statistics for export operation.

commits_total counts the commits that actually land in the destination: it is derived from the same branch/tag ref set (collect_ref_updates) that copy_mirror_to_path copies, by walking the commit ancestry of those tips. Counting from the copy path — rather than a parallel walk over current Heddle refs — guarantees the reported total equals what’s copied, including a stale mirror ref left behind by a dropped thread (export does not prune mirror refs, so that commit still travels and is still counted). states_exported is the freshly-minted subset of that same copied ref set — both counts are partitions of one walk, so states_exported + already == commits_total holds by construction and a state minted into the mirror but reachable from no copied ref (an orphan dropped-thread history) inflates neither. They diverge whenever the destination is already populated: an overlay re-export reports commits_total = N and states_exported = 0 — the signal that surfaces “already in sync” instead of a misleading bare “exported 0 states” (heddle#289, mirroring the import-side commits_imported/states_created split from heddle#147).

Fields

states_exported: usize

Freshly-minted git commits that land in the destination — the subset of the copied ref set’s commits minted during this export (no preserved git_oid). Stays at 0 when every copied commit was already mapped to an existing commit. A minted commit reachable from no copied ref is excluded (it never reaches the destination).

commits_total: usize

Unique commits reachable from the branch/tag tips copied to the destination, including ones whose commit already existed and any carried by a stale mirror ref. Mirrors ImportStats::commits_imported.

threads_synced: usize

markers_synced: usize

branches: Vec<ExportedRef>

Branches written to the destination, paired with their tip commit so the summary can show tip short-SHAs.

tags: Vec<ExportedRef>

Tags written to the destination, paired with their tip commit.

failed_refs: Vec<(String, FailedRefExportReason)>

Refs this export could NOT publish, paired with why – the fail-soft counterpart of branches/tags (heddle#261). Export continues past a failed ref and records it here rather than aborting on the first one, so a single branch that moved on the Git side cannot mask the outcome of every ref behind it. Keyed by FULL ref name (refs/heads/foo), the same spelling the reconcile loops use. Mirrors the import side’s ImportStats::skipped_non_commit_refs reporting: the operation succeeds at what it could do and reports the remainder, and the caller exits non-zero when this is non-empty.
