105d70e9743f651d141c6e0d901d60d583afd4d9 ref(hwi): Move hwi out of bdk (Daniela Brozzoni) Pull request description: Fixes #872 ### Description This commit moves the `hardwaresigner` outside of bdk and inside `bdk_hwi` ### Notes to the reviewers There are currently two issues with the code: - `TransactionSigner` dictates that `sign_transaction` must return a `SignerError` - but being `SignerError` defined inside of bdk, we can't modify it to include an hwi specific error! I don't know how we could fix this (other than getting rid of the trait altogether :)); for now I just added a `SignerError::Generic` variant, lmk if you have better ideas! - The hwi tests used the bdk utils to get a funded wallet for testing, which aren't available in `bdk_hwi`, which made me realize - maybe we should expose them so that we can use them across our crates, and also our users can use them to test their code? For now, I just left the test commented. ### Changelog notice - The old `hardwaresigner` module has been moved out of `bdk` and inside `bdk_hwi`. ### 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: ~~* [ ] I've added tests for the new feature~~ * [x] I've added docs for the new feature ACKs for top commit: notmandatory: reACK 105d70e9743f651d141c6e0d901d60d583afd4d9 Tree-SHA512: 9ae3cd035cc27bd7b2831e89c104f40771c6f165cb3bfe1a9052f820050fca7c19f4dd68f171c630a71a7d18ccdee5f94adbc497c6475bd257c2d01cc08109a1
The Bitcoin Dev Kit
BDK

A modern, lightweight, descriptor-based wallet library written in Rust!
Project Homepage | Documentation
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
v1.0
which 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 levelWallet
type 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-client
crate with methods to fetch chain data from an esplora HTTP server in the form thatbdk_chain
andWallet
can consume.electrum
: Extends theelectrum-client
crate with methods to fetch chain data from an electrum server in the form thatbdk_chain
andWallet
can 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_cli
and theelectrum
crate. It shows the power of the bdk tools (chain
+file_store
+electrum
), without depending on the mainbdk
library.wallet_esplora_blocking
: Uses theWallet
to sync and spend using the Esplora blocking interface.wallet_esplora_async
: Uses theWallet
to sync and spend using the Esplora asynchronous interface.wallet_electrum
: Uses theWallet
to 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"
