Trait IntoSystem 

pub trait IntoSystem<Marker> {
    type System: System;

    // Required method
    fn into_system(self) -> Self::System;
}

Converts a function (or closure) with valid system parameters into a System that can be registered with App::add_system.

Implemented via the [impl_system!] macro for function arities 0–8.

Required Associated Types

type System: System

Required Methods

fn into_system(self) -> Self::System

Dyn Compatibility

This trait is dyn compatible.

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