fac228337c79e1a7c406500c177e049e7f9f5da7 feat(chain)!: make `KeychainTxOutIndex` more range based (LLFourn) Pull request description: KeychainTxOut index should try and avoid "all" kind of queries. There may be subranges of interest. If the user wants "all" they can just query "..". The ideas is that KeychainTxOutIndex should be designed to be able to incorporate many unrelated keychains that can be managed in the same index. We should be able to see the "net_value" of a transaction to a specific subrange. e.g. imagine a collaborative custody service that manages all their user descriptors inside the same `KeychainTxOutIndex`. One user in their service may pay another so when you are analyzing how much a transaction is spending for a particular user you need to do analyze a particular sub-range. ### Notes to the reviewers - I didn't change `unused_spks` to follow this rule because I want to delete that method some time in the future. `unused_spks` is being used in the examples for syncing but it shouldn't be (the discussion as to why will probably surface in #1194). - I haven't applied this reasoning to the methods that return `BTreeMap`s e.g. `all_unbounded_spk_iters`. It probably should be but I haven't made up my mind yet. This probably belongs after #1194 ### Changelog notice - `KeychainTxOutIndex` methods modified to take ranges of keychains 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 #### New Features: * [x] I've added tests for the new feature * [x] I've added docs for the new feature ACKs for top commit: evanlinjin: ACK fac228337c79e1a7c406500c177e049e7f9f5da7 Tree-SHA512: ec1e75f19d79f71de4b6d7748ef6da076ca92c2f3fd07e0f0dc88e091bf80c61268880ef78be4bed5e0dbab2572e22028f868f33e68a67d47813195d38d78ba5
The Bitcoin Dev Kit
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.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 mainbdklibrary.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 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"
# proptest 1.4.0 has MSRV 1.65.0
cargo update -p proptest --precise "1.2.0"
