00ec19ef2dci: fix MSRV pinning for rustls 0.21.9 (Steve Myers)77f9977c02feat(wallet): Add infallible Wallet get_address(), get_internal_address functions (Steve Myers)9e7d99e3bfrefactor(bdk)!: add context specific error types, remove top level error mod (Steve Myers) Pull request description: ### Description To remove some places where there were `.expect("TODO")` I added a new `CreateTxError` type which is returned from `TxBuilder::finish()`. I also updated related tests and doc tests. Fixes https://github.com/bitcoindevkit/bdk/issues/996#issuecomment-1621036206 Also added fallible `Wallet::try_get_address()` and `try_get_internal_address()` to return `Result` with a possible `D:WriteError` when a PersistBackend is used. This should fix #996. I removed catch-all bdk::Error and replaced usages with new types and updated related functions, fixes #994. ### Notes to the reviewers ~~I didn't add all possible bdk::Error types that `Wallet::create_tx()` and `TxBuilder::finish()` functions might throw. It's probably not too much more work but will take a bit more research so I want to make sure this is the right general approach first.~~ I added `anyhow` to the dev-dependencies so I could remove some `.expect()` lines from the docs tests and make the examples closer to what an end user should do. I also used the `anyhow!()` macro to replace a few places that were using the `bdk::Error::Generic` in example code. I also moved the module level error.rs file to wallet/error.rs so no one would be tempted to make any new catch all errors and to make it clear that all the errors in it are wallet module related. ### Changelog notice Changed - Updated bdk module to use new context specific error types - wallet: MiniscriptPsbtError, CreateTxError, BuildFeeBumpError error enums - coin_selection: module Error enum - Renamed fallible Wallet address functions to try_get_address() and try_get_internal_address() Removed - Removed catch-all top level bdk::Error enum - Removed impl_error macro Added - Added infallible Wallet get_address(), get_internal_address functions ### 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 * [ ] I've added tests to reproduce the issue which are now passing * [ ] I'm linking the issue being fixed by this PR Top commit has no ACKs.

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.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.
