Difficulty borrowing parameters with EventStream!

[Taztingo]

I'm having some difficulty getting the EventStream! macro to borrow parameters. I followed the documentation and included Event + _' but it's complaining that Event from EventStream! is not a trait. I wrote some sample code that just clones a string from a parameter. I'm newish to rust so I'm not the best with macros and lifetimes. Any help and explanation would be greatly appreciated!

#[get("/my/stream")]
pub fn my_stream(config: & State<config::Config>, _pool: &State<Pool<Sqlite>>) -> EventStream![Event + '_] {
    EventStream! {
        let _test = config.database.clone();
        let mut id = 0;
        let mut interval = time::interval(Duration::from_secs(1));
        loop {
            yield Event::data("test data").event("test").id(id.to_string());
            interval.tick().await;
            id += 1;
        }
    } 
}

The following is the error i receive:

pub fn my_stream(config: & State<config::Config>) -> EventStream![Event + '_] {
   |                                                                                    ^^^^^ not a trait

help: `+` is used to constrain a "trait object" type with lifetimes or auto-traits; structs and enums can't be bound in that way

Bonus points... I put a question on stackoverflow for this. https://stackoverflow.com/questions/69577423/cant-get-rockets-eventstream-to-work-with-borrowed-values

I ended up extracting the the logic that incorporates the parameters outside of the EventStream macro. I'm not sure what the proper fix is, but this is what the chat example did and it allowed me to bypass the issue.
