Trait System 

pub trait System: 'static {
    // Required method
    fn run(&mut self, world: &World, resources: &Resources);
}

A runnable system — the type-erased form IntoSystem produces, so different systems (different parameter lists) can live in the same Vec<Box<dyn System>>.

Required Methods

fn run(&mut self, world: &World, resources: &Resources)

Dyn Compatibility

This trait is dyn compatible.

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