Struct Dep 

pub struct Dep<T>(pub T);

Newtype wrapper used in #[handler] function signatures to declare a handler dependency.

When the macros feature is enabled and a handler function accepts parameters of the form Dep(name): Dep<MyType>, the generated descriptor will resolve MyType from Deps at build time and inject it into the handler.

You can also use Dep<T> in manual HandlerDescriptor implementations to make the injection contract explicit:

use jaeb::{Dep, Deps};
use std::sync::Arc;

struct Mailer;

fn uses_dep(dep: Dep<Arc<Mailer>>) {
    let _mailer: &Arc<Mailer> = &*dep;
}
