Return result/option from a system

[bold mason]

Is it possible to return result or option from a system? i want it use mostly for the ? syntax. When I try to do that I get "trait not satisfied" error on adding the system

Yep! Check out this example: https://github.com/bevyengine/bevy/blob/latest/examples/ecs/system_piping.rs

There's also a bevy sys fail crate to add sugar

Also there is the traditional approach

(|| -> Result<A, B> {
   f1()?;
   f2()?;
   Ok(f3()?) 
})().unwrap()
