* `ElectrumUpdate::missing_full_txs` now returns a `Vec<Txid>` so we don't keep a reference to the passed-in `graph`. * `ElectrumUpdate::finalize*` methods now takes in `missing` txids instead of `full_txs`. `Client::batch_transaction_get` is called within the methods. Other changes: * `wallet::ChangeSet` is now made public externally. This is required as a wallet db should implement `PersistBackend<wallet::ChangeSet>`.

About
The bdk libraries aims to provide well engineered and reviewed components for Bitcoin based applications.
It is built upon the excellent rust-bitcoin and rust-miniscript crates.
⚠ The Bitcoin Dev Kit developers are in the process of releasing a
v1.0which is a fundamental re-write of how the library works. See for some background on this project: https://bitcoindevkit.org/blog/road-to-bdk-1/ (ignore the timeline 😁) For a release timeline see thebdk_core_stagingrepo where a lot of the component work is being done. The plan is that everything in thebdk_core_stagingrepo will be moved into thecratesdirectory here.
Architecture
The project is split up into several crates in the /crates directory:
bdk: Contains the central high levelWallettype that is built from the low-level mechanisms provided by the other componentschain: Tools for storing and indexing chain datafile_store: A (experimental) persistence backend for storing chain data in a single file.esplora: Extends theesplora-clientcrate with methods to fetch chain data from an esplora HTTP server in the form that [bdk_chain] andWalletcan consume.electrum: Extends theelectrum-clientcrate with methods to fetch chain data from an electrum server in the form that [bdk_chain] andWalletcan consume.
Fully working examples of how to use these components are in /example-crates
