Instead of relying on a `OwnedIndexer` trait to filter for relevant txouts, we move the listing and balance methods from `IndexedTxGraph` to `TxGraph` and add an additional input (list of relevant outpoints) to these methods. This provides a simpler implementation and a more flexible API.

Previously, regardless of whether writing to persistence backend is successful or not, the logic always cleared `self.staged`. This is changed to only clear `self.staged` after successful write. Additionally, the written changeset (if any) is returned, and `PersistBackend::write_changes` will not be called if `self.staged` is empty.
Rename the `S` trait bound to `OI` (outpoint index) to emphasize it's not only for spk indexing.

Description
As noted in #971 (comment).
Instead of relying on a
OwnedIndexertrait to filter for relevant txouts, we move the listing and balance methods fromIndexedTxGraphtoTxGraphand add an additional input (list of relevant outpoints) to these methods.This provides a simpler implementation and a more flexible API.
Other Fixes
The
Persist::commitmethod is fixed in 96b1075.Previously, regardless of whether writing to persistence backend is successful or not, the logic always cleared
self.staged. This is changed to only clearself.stagedafter successful write.Additionally, the written changeset (if any) is returned, and
PersistBackend::write_changeswill not be called ifself.stagedis empty.Notes to the reviewers
Yes, slightly more boilerplate to do the same things, but less code to maintain and a much more flexible API. Very worth it IMO.
