- The KeychainTxOutIndex's internal SpkIterator now uses DescriptorId
instead of K. The DescriptorId -> K translation is made at the
KeychainTxOutIndex level.
- The keychain::Changeset is now a struct, which includes a map for last
revealed indexes, and one for newly added keychains and their
descriptor.
API changes in bdk:
- Wallet::keychains returns a `impl Iterator` instead of `BTreeMap`
- Wallet::load doesn't take descriptors anymore, since they're stored in
the db
- Wallet::new_or_load checks if the loaded descriptor from db is the
same as the provided one
API changes in bdk_chain:
- `ChangeSet` is now a struct, which includes a map for last revealed
indexes, and one for keychains and descriptors.
- `KeychainTxOutIndex::inner` returns a `SpkIterator<(DescriptorId, u32)>`
- `KeychainTxOutIndex::outpoints` returns a `impl Iterator` instead of `&BTreeSet`
- `KeychainTxOutIndex::keychains` returns a `impl Iterator` instead of
`&BTreeMap`
- `KeychainTxOutIndex::txouts` doesn't return a ExactSizeIterator
anymore
- `KeychainTxOutIndex::unbounded_spk_iter` returns an `Option`
- `KeychainTxOutIndex::next_index` returns an `Option`
- `KeychainTxOutIndex::last_revealed_indices` returns a `BTreeMap`
instead of `&BTreeMap`
- `KeychainTxOutIndex::reveal_to_target` returns an `Option`
- `KeychainTxOutIndex::reveal_next_spk` returns an `Option`
- `KeychainTxOutIndex::next_unused_spk` returns an `Option`
- `KeychainTxOutIndex::add_keychain` has been renamed to
`KeychainTxOutIndex::insert_descriptor`, and now it returns a
ChangeSet
