Custom command await / async

[boreal spade]

Hi everyone,
is there a way to run custom commands async to wait until the command is finished, like in js?

fn startup( mut commands: Commands, ) { await commands.custom(); println!("Done"); }

Sure, you can use a task - the examples on tasks can technically be entirely done within commands

But I would hesitate to do anything like that - Commands are specifically designed to block the world for the least possible amount of time, and waiting on anything within one defeats that

bevy_defer is exactly made for this use case 🙂

I'll also throw in bevy_mod_async. Not as fancy as bevy_defer, but similar problem space
