Trait IntoSystemConfig 

pub trait IntoSystemConfig<Params>: IntoSystem<Params> + Sized {
    // Required methods
    fn after<S2, P2>(self, other: S2) -> SystemConfig<Self, Params>
       where S2: IntoSystem<P2> + 'static;
    fn before<S2, P2>(self, other: S2) -> SystemConfig<Self, Params>
       where S2: IntoSystem<P2> + 'static;
}

Lets .after(...)/.before(...) be called directly on a system — a plain function, closure, or anything else IntoSystem is implemented for — to declare where it must run relative to another system in the same Schedule:

schedule
    .add_system(spawn_enemies)
    .add_system(move_enemies.after(spawn_enemies))
    .add_system(render.after(move_enemies));

Required Methods

fn after<S2, P2>(self, other: S2) -> SystemConfig<Self, Params>

where S2: IntoSystem<P2> + 'static,

Wraps this system with a constraint that it must run after other.

fn before<S2, P2>(self, other: S2) -> SystemConfig<Self, Params>

where S2: IntoSystem<P2> + 'static,

Wraps this system with a constraint that it must run before other.

Dyn Compatibility

This trait is not dyn compatible.

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