Trait SystemOrderingExt 

pub trait SystemOrderingExt<Marker>: IntoSystem<Marker> + Sized {
    // Provided methods
    fn after<F, Marker2>(self, system: F) -> Labeled<Self::System>
       where F: IntoSystem<Marker2> + 'static { ... }
    fn before<F, Marker2>(self, system: F) -> Labeled<Self::System>
       where F: IntoSystem<Marker2> + 'static { ... }
}

Adds .after()/.before() to any system, for declaring run-order constraints relative to other systems in the same stage — referenced directly by their function/closure, no string labels needed.

app.add_system(SystemStage::Update, physics_step);
app.add_system(SystemStage::Update, apply_damage.after(physics_step));

Provided Methods

fn after<F, Marker2>(self, system: F) -> Labeled<Self::System>

where F: IntoSystem<Marker2> + 'static,

Require that system runs before this one, within the same stage.

fn before<F, Marker2>(self, system: F) -> Labeled<Self::System>

where F: IntoSystem<Marker2> + 'static,

Require that system runs after this one, within the same stage.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
