A `wallet_rpc` example is added to demonstrate syncing `bdk::Wallet` with the `bdk_bitcoind_rpc` chain-source crate. The API of `bdk_bitcoind_rpc::Emitter` is changed so the receiver knows how to connect to the block emitted. ### Notes to the reviewers ### Changelog notice Added * `Wallet` methods to apply full blocks (`apply_block` and `apply_block_connected_to`) and a method to apply a batch of unconfirmed transactions (`apply_unconfirmed_txs`). * `CheckPoint::from_block_ids` convenience method. * `LocalChain` methods to apply a block header (`apply_header` and `apply_header_connected_to`). * Test to show that `LocalChain` can apply updates that are shorter than original. This will happen during reorgs if we sync wallet with `bdk_bitcoind_rpc::Emitter`. Fixed * `InsertTxError` now implements `std::error::Error`. #### All Submissions: * [x] I've signed all my commits * [x] I followed the [contribution guidelines](https://github.com/bitcoindevkit/bdk/blob/master/CONTRIBUTING.md) * [x] I ran `cargo fmt` and `cargo clippy` before committing #### New Features: * [x] I've added tests for the new feature * [x] I've added docs for the new feature ACKs for top commit: LLFourn: self-ACK: a4f28c079e3bc4500e8329aeed230d8100d38617 evanlinjin: ACK a4f28c079e3bc4500e8329aeed230d8100d38617 Tree-SHA512: e39fb65b4e69c0a6748d64eab12913dc9cfe5eb8355ab8fb68f60a37c3bb2e1489ddd8f2f138c6470135344f40e3dc671928f65d303fd41fb63f577b30895b60

BDK
A modern, lightweight, descriptor-based wallet library written in Rust!

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 1.0 project page.
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 thatbdk_chainandWalletcan consume.electrum: Extends theelectrum-clientcrate with methods to fetch chain data from an electrum server in the form thatbdk_chainandWalletcan consume.
Fully working examples of how to use these components are in /example-crates:
example_cli: Library used by theexample_*crates. Provides utilities for syncing, showing the balance, generating addresses and creating transactions without using the bdkWallet.example_electrum: A command line Bitcoin wallet application built on top ofexample_cliand theelectrumcrate. It shows the power of the bdk tools (chain+file_store+electrum), without depending on the mainbdklibrary.wallet_esplora_blocking: Uses theWalletto sync and spend using the Esplora blocking interface.wallet_esplora_async: Uses theWalletto sync and spend using the Esplora asynchronous interface.wallet_electrum: Uses theWalletto sync and spend using Electrum.
Minimum Supported Rust Version (MSRV)
This library should compile with any combination of features with Rust 1.63.0.
To build with the MSRV you will need to pin dependencies as follows:
# zip 0.6.3 has MSRV 1.64.0
cargo update -p zip --precise "0.6.2"
# time 0.3.21 has MSRV 1.65.0
cargo update -p time --precise "0.3.20"
# jobserver 0.1.27 has MSRV 1.66.0
cargo update -p jobserver --precise "0.1.26"
# home 0.5.9 has MSRV 1.70.0
cargo update -p home --precise "0.5.5"
