Trait System 

pub trait System {
    // Required methods
    fn name(&self) -> &'static str;
    fn run(&mut self, world: &mut World);
    fn access(&self) -> Vec<Access>;
}

Trait-object interface for all system types.

Required Methods

fn name(&self) -> &'static str

Human-readable system name (for diagnostics and conflict messages).

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

Run the system against the world.

fn access(&self) -> Vec<Access>

Declare what world data this system accesses.

Returns the union of all parameter accesses for parameterized systems.

Dyn Compatibility

This trait is dyn compatible.

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