[−][src]Struct world_dispatcher::System
Struct used to run a system function using the world.
This struct is also used internally by the Dispatcher
to coherent
execution sequence.
Implementations
impl System
[src]
pub fn initialize(&self, world: &mut World)
[src]
Initializes the resources required to run this system inside of the
provided World
, if those resources don't already exist.
This is called automatically if you use a Dispatcher
, so in most
cases it is not required to call it manually.
pub fn run(&mut self, world: &World) -> SystemResult
[src]
Runs the system's function using the provided World
's resources.
