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 #996 (comment)

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.

Thank you for taking this on!

I appreciate your attempt to be conservative in the amount of changes made. However, the current state of this PR does not result in a better API since the caller still has to handle a large list of redundant error variants.

If it was a PR to purely remove the .expect("TODO")s, I would just return a bdk::Error::Generic or introduce a new variant in bdk::Error.

However, I would prefer this PR to fix the error-handling API for tx creation completely (as it seems you already have done the majority of the work).

But we probably just need a quick fix for the next release.

I removed the CreateTxError::Bdk variant and moved all the needed variants from the bdk::Error to the CreateTxError enum, plus created concrete variants for any errors that were using Generic. A few other things I'd like to do, but don't need to be in this PR:

  • add BuildFeeBumpError enum for Wallet::build_fee_bump
  • add SignError enum for Wallet::sign
  • add FinalizeError enum for Wallet::finalize
  • eliminate (or greatly diminish) bdk::Error
  • move the wallet error enums and related code to a wallet::error file
  • add fallible and infallible versions of any others Wallet functions it makes sense for

@notmandatory we didn't talk about this PR in the last calls. Is it correct to keep it into alpha.3 milestone? Shall we discuss it in the next call?

I don't think we need to discuss it until after alpha.2 is released. Then I'll have to rebase it and fix a few small things and will bug folks for a re-review.

I've removed the cfg for fmt::Display and created a new issue for that change (if we want to do it). Tests passing and ready for re-review.

I pushed a couple more commits to add changes suggested by @ValuedMammal. I'll squash commits to clean up the history prior to merging.

I don't think this should be addressed in this PR, but I think we should use idiomatic naming for methods: https://rust-lang.github.io/api-guidelines/naming.html#getter-names-follow-rust-convention-c-getter

I.e. Wallet::get_address should be Wallet::address.

Thank you for this work. Now the errors are more domain-specific and detailed.

Fantastic work, than you.

I think Lloyd's comment should be fixed, as it should be fairly trivial. I left a comment on that.

Ohhhh! 🤦‍♂️ thanks for the help here, now I get it. I'm going to push your fix, rebase, clean up the history a little, and then it should be ready to merge.
