Is there way to specify an external crate for auto discovery?

[that-ambuj]

Hi, I have forked a rust project which has a lot of huge types, so I've added utoipa::ToSchema on all the types but now I need register them recursively, which is a lot of work.

I've seen that this library takes path to the module. Is there any way I can specify the module of an external crate like some_lib::api and it would work on that?

The only hack I can think of is to put the git repo as submodule and a cargo workspace member and then specify the path. I hope there is a better solution or one that can be implemented.

You can use the from keyword to imports from another crate
#[utoipauto(paths = "./utoipauto/src from utoipauto")]
But I've only used it to import models from another crate that was still in the same workspace.

I think you could technically make it work by finding the downloaded path of the external crate and import from here but it don't think it's a good idea.
There's definitely a big room for improvement in this field.
but I don't really see how we could do it from a crate level...

If it's a big dependency that is very important to your project, I'd suggest that you inline it like you said.

I recently thought about how to solve this.

I would agree that scanning the actual source code is not a good idea.
I can tackle the implementation but I would love if somebody could help me find an actual good concept for it.

Maybe there is a crate that "implements" reflections (but at compile-time)?
Maybe even a crate that already supports scanning dependencies?

But I already thought about some requirements:

• only scan defined dependencies
• do not increase compile time drastically

Few crates I have come across for reflection in Rust are https://github.com/EmbarkStudios/mirror-mirror https://github.com/dtolnay/reflect, But they do not provide "package" found in Java to loop over jars. reflection and needs a macro for the types thus does not seem viable option I guess.

I guess that crates that implement utoipa have a struct that implement OpenApi and hopefully exposes it.
I am not sure but if utoipa has a merge Feature tuen this can be Utilitized (still you have to List all the crates manually).

I currently have not the Capacity to implement this Feature.
