(Wei Chen) 4edf533b678cb21f4c29ded22692e607ff75e2cd chore: extract `TestEnv` into separate crate `TestEnv` is extracted into its own crate to serve as a framework for testing other block explorer APIs. (Wei Chen) 6e648fd5afa188290b05f8e050ba69fe5f8b80e4 chore: update MSRV dependency for nightly docs (Wei Chen) Pull request description: ### Description `TestEnv` is extracted into its own crate with `electrsd` support added so that `TestEnv` can also serve `esplora` and `electrum`. The tests in the `esplora` crate have also been updated to use `TestEnv`. The `tx_can_become_unconfirmed_after_reorg()` test in `test_electrum` suggests that the electrum issue where a reorged tx would be stuck at confirmed does not exist anymore. ### Notes to the reviewers The code for `tx_can_become_unconfirmed_after_reorg()` was adapted from the same test in `bitcoind_rpc/test_emitter`. This electrum version of the test requires extra review, as I am uncertain if I used the API efficiently. #### 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 ACKs for top commit: evanlinjin: ACK 7c9ba3cfc855dc0845476fe923dac4e47cb5c06a Tree-SHA512: 36c6501e477abb7ae68073b6f4776f1f69f8964010ab758aa3677aae96df10f2cb632421872cacd73b37123d6db8a9dbefb5b6416e0dd524b712bf3fc56b7139
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.example_esplora
: A command line Bitcoin wallet application built on top ofexample_cli
and theesplora
crate. It shows the power of the bdk tools (chain
+file_store
+esplora
), without depending on the mainbdk
library.example_bitcoind_rpc_polling
: A command line Bitcoin wallet application built on top ofexample_cli
and thebitcoind_rpc
crate. It shows the power of the bdk tools (chain
+file_store
+bitcoind_rpc
), 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"
