Good work 👍

A couple of "meta" pieces of feedback:

• it would would have been easier to review if the fix of the typo for AuthorizationDetailsProfile had been in a separate commit
• in general, at least listing the changes in the PR description if not through commits would have been helpful

I've left a couple comments in places, but it broadly looks good to me. It's rather difficult to look at the spec and try to figure out if the code is missing anything, but I didn't spot anything!

• can we rename IssuerMetadata to CredentialIssuerMetadata to align with the naming in the spec? maybe people disagree with me, but I'd prefer a 1:1 naming mapping
• update jwt.rs and ldp.rs to use credential_signing_alg_values_supported instead of cryptographic_suites_supported
• update CredentialMetadata tests to new version
  • add background image in tests
  • replace cryptographic_suites_supported with credential_signing_alg_values_supported
  • can we add an example test for jwtld.rs ?
• typo: field setters -> “set_proof_types_suuported”

no support for sd-jwt-vc (probably for the future)

After some discussion above, I've pushed a "forgiving" version of the server selection with comments outlining which situations could also be interpreted as errors.
Now, I think this just needs a last Rust-specific review on the latest commit.

Sorry I missed that in your proposed snippet. tracing is the globally accepted logging crate and we should just use that. But in general, it's only in very specific cases that you would pass around function and in general you would rely on a trait.

[theosirian]

I've replaced log_and_continue and added spans on the outer and inner functions. Is there anything else that we should be logging in those functions besides what I added?

[sbihel]

maybe but that's something we'll discover organically, we've got the most important things in place
