JoJoJet	5efc226290	Allow piping run conditions (#7547) ... # Objective Run conditions are a special type of system that do not modify the world, and which return a bool. Due to the way they are currently implemented, you can *only* use bare function systems as a run condition. Among other things, this prevents the use of system piping with run conditions. This make very basic constructs impossible, such as `my_system.run_if(my_condition.pipe(not))`. Unblocks a basic solution for #7202. ## Solution Add the trait `ReadOnlySystem`, which is implemented for any system whose parameters all implement `ReadOnlySystemParam`. Allow any `-> bool` system implementing this trait to be used as a run condition. --- ## Changelog + Added the trait `ReadOnlySystem`, which is implemented for any `System` type whose parameters all implement `ReadOnlySystemParam`. + Added the function `bevy::ecs::system::assert_is_read_only_system`.	2023-02-07 22:22:16 +00:00
