Dependency injection?

[DenuxPlays]

Hello,
I've wondered if there is a way to implement "dependency injection" of some kind.
My basic goal is to make this workl:

#[get("/user/{user_id}")]
pub async fn get_one(user: User) -> impl Responder {
    // Some more operations
    retrun HttpResponse::Ok().json(user);
}

The things is that user needs to have access to the user_id and the identity (from actixcidentity crate).
I found the FromRequest trait but not sure if I can make this work with that or if there is a simpler way.
Of course I could implement that logic for every endpoint but this would result in a lot of code duplication even if I create an extra function that returns the user or an error.

Is there any way to make this work?

Edit:
The FromRequest trait is not async so as I use sea-orm (an async ORM) I cannot utilize the FromRequest trait.

The FromRequest trait support async operations, see docs: https://docs.rs/actix-web/latest/actix_web/trait.FromRequest.html#associatedtype.Future

I'd suggest that creating an extractor (impl FromRequest) is the right way of achieving your goal here.

Ah okay
Gonna try this sounds promising
Thank you 🙏
