Transforming custom domain/application/infrastructure errors into huma HTTP errors

[tomflenner]

Hello 👋🏻 !

I am new to huma framework and thanks for bringing this to the community that looks really awesome 🔥.

Coming from a .NET background and quite not super familiar with go and idiomatic Go - I am currently testing huma for a side project.

Wanted to know what is the best way to transform custom errors that are in domain/application/infrastructure layers so basically some custom error that represent some failure in a use case into a huma http error.

For example :

type MyNotFoundError struct {}

into a huma.Error404NotFound

The idea is not to introduce huma framework in my domain/application/infrastructure layers and only keep that for the HTTP (API layer).

This may not be Go idiomatic but I would like to start like that.

Thanks a lot, feedback is appreciated if I am doing wrong Go here !🙏🏻

I think it's somehow related to this :

But I am not sure how I need to implement without loosing the full problem details. I would love to override only title, detail and status nothing more.
