Trait bevy::ecs::prelude::IntoSystem

pub trait IntoSystem<In, Out, Params>: Sized {
    type System: System<In = In, Out = Out>;

    fn into_system(this: Self) -> Self::System;
}

Conversion trait to turn something into a System.

Use this to get a system from a function. Also note that every system implements this trait as well.

Examples

use bevy_ecs::prelude::*;

fn my_system_function(a_usize_local: Local<usize>) {}

let system = IntoSystem::into_system(my_system_function);

Required Associated Types

type System: System<In = In, Out = Out>

Required Methods

fn into_system(this: Self) -> Self::System

Turns this value into its corresponding System.
