a577c22b12f4edf0b2f2f266fb13656caf1d21c4 fix(persist): add default feature to enable bdk_chain/std (Steve Myers) Pull request description: ### Description This PR adds a `default` feature to `bdk_persist` so it can be build on its own. Once #1422 is done we can remove the `default`again. ### Notes to the reviewers I need to be able to build `bdk_persist` on its own so I can publish it to crates.io. ### 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 ACKs for top commit: ValuedMammal: ACK a577c22b12f4edf0b2f2f266fb13656caf1d21c4 oleonardolima: ACK a577c22b12f4edf0b2f2f266fb13656caf1d21c4 storopoli: ACK a577c22b12f4edf0b2f2f266fb13656caf1d21c4 Tree-SHA512: 8b07a9e4974dec8812ca19ce7226dcaece064270a0be8b83d3c326fdf1e89b051eb0bd8aa0eda9362b2c8233ecd6003b70c92ee046603973d8d40611418c3841

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 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 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"
