Trait IntoSystem 

pub trait IntoSystem<Marker>: SealedSystem<Marker> { }

A function that can be added to a Schedule as a system.

Implemented for functions (and closures) of up to 8 SystemParams returning a SystemOutput; Marker only tells the implementations apart. The trait is sealed.

use pragma_ecs::{IntoSystem, Res, View};

struct Speed(f32);

fn movement(_: View<&mut f32>, _: Res<Speed>) {}

fn assert_system<M>(_: impl IntoSystem<M>) {}
assert_system(movement);

Dyn Compatibility

This trait is dyn compatible.

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