Objective

  • have errors in configure_set and configure_sets show the line number of the user calling location rather than pointing to schedule.rs
  • use display formatting for the errors

Example Error Text

// dependency loop
// before
thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: DependencyLoop("A")', crates\bevy_ecs\src\schedule\schedule.rs:682:39
// after
thread 'main' panicked at 'System set `A` depends on itself.', examples/stress_tests/bevymark.rs:16:9

// hierarchy loop
// before
thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: HierarchyLoop("A")', crates\bevy_ecs\src\schedule\schedule.rs:682:3
// after
thread 'main' panicked at 'System set `A` contains itself.', examples/stress_tests/bevymark.rs:16:9

// configuring a system type set
// before
thread 'main' panicked at 'configuring system type sets is not allowed', crates\bevy_ecs\src\schedule\config.rs:394:9
//after
thread 'main' panicked at 'configuring system type sets is not allowed', examples/stress_tests/bevymark.rs:16:9

Code to produce errors:

use bevy::prelude::*;

#[derive(SystemSet, Clone, Debug, PartialEq, Eq, Hash)]
enum TestSet {
    A,
}

fn main() {
    fn foo() {}
    let mut app = App::empty();
    // Hierarchy Loop
    app.configure_set(Main, TestSet::A.in_set(TestSet::A));
    // Dependency Loop
    app.configure_set(Main, TestSet::A.after(TestSet::A));
    // Configure System Type Set
    app.configure_set(Main, foo.into_system_set());
}
