There the `SpkTxOutIndex<(K,u32)>` was changed to `SpkTxOutIndex<(DescriptorId, u32>)`. This led to a complicated translation logic in `KeychainTxOutIndex` (where the API is based on `K`) to transform calls to it to calls to the underlying `SpkTxOutIndex` (which now indexes by `DescriptorId`). The translation layer was broken when it came to translating range queries from the `KeychainTxOutIndex`. My solution was just to revert this part of the change and remove the need for a translation layer (almost) altogether. A thin translation layer remains to ensure that un-revealed spks are filtered out before being returned from the `KeychainTxOutIndex` methods. I feel like this PR could be extended to include a bunch of ergonomics improvements that are easier to implement now. But I think that's the point of https://github.com/bitcoindevkit/bdk/pull/1451 so I held off and should probably go and scope creep that one instead. ### Checklists #### 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 #### Bugfixes: * [x] This pull request breaks the existing API * [x] I've added tests to reproduce the issue which are now passing * [x] I'm linking the issue being fixed by this PR ACKs for top commit: evanlinjin: ACK8dd174479fTree-SHA512: 283e6b6d4218902298e2e848fe847a6c85e27af4eee3e4337e3dad6eacf9beaa08ac99b1dce7b6fb199ca53931e543ea365728a81c41567a2e510cce77b12ac0

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:
wallet: Contains the central high levelWallettype that is built from the low-level mechanisms provided by the other componentschain: Tools for storing and indexing chain datapersist: Types that define data persistence of a BDK walletfile_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 bdk_walletWallet.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 mainbdk_walletlibrary.example_esplora: A command line Bitcoin wallet application built on top ofexample_cliand theesploracrate. It shows the power of the bdk tools (chain+file_store+esplora), without depending on the mainbdk_walletlibrary.example_bitcoind_rpc_polling: A command line Bitcoin wallet application built on top ofexample_cliand thebitcoind_rpccrate. It shows the power of the bdk tools (chain+file_store+bitcoind_rpc), without depending on the mainbdk_walletlibrary.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:
cargo update -p zstd-sys --precise "2.0.8+zstd.1.5.5"
cargo update -p time --precise "0.3.20"
cargo update -p home --precise "0.5.5"
cargo update -p proptest --precise "1.2.0"
cargo update -p url --precise "2.5.0"
