really awesome PR @Farhad-Shabani ! Really like the solution. 👍

I asked for some clarifications in the comments.

If I have a context with trait-bounded generics as following:

struct MyIbcContext<T: MyTrait> { ... }

How do I the trait-bound its generics while deriving IbcClientState? The following doesn't work.

#[derive(IbcClientState)]
#[validation(MyIbcContext<T: MyTrait>)]
#[execution(MyIbcContext<T: MyTrait>)]
enum AnyClientState { ... }

What about this?

#[derive(IbcClientState)]
 #[validation(MyIbcContext<T>)]
 #[execution(MyIbcContext<T>)]
 enum AnyClientState { ... }

[rnbguy]

The trait bounds are needed when we are deriving the ClientState{Validation, Execution} 😅

Ahh, that's right. That's a new case!
