Trait TaskComponent

Source 
pub trait TaskComponent<'a>: Component {
    type Data: SystemData<'a>;

    // Required method
    fn run(&mut self, data: &mut Self::Data) -> bool;
}
Expand description

An ephemeral component that needs access to SystemData to run some task. Will be run by the TaskRunnerSystem<T> until run returns true.

Note: TaskComponent::Data isn’t allowed to contain Storage<TaskComponent>, since the TaskRunnerSystem already uses that resource and borrows it mutably while calling TaskComponent::run. If you really need access to Storage<TaskComponent>, you can safely use the LazyUpdate resource for that.

Required Associated Types§

Source

type Data: SystemData<'a>

Required Methods§

Source

fn run(&mut self, data: &mut Self::Data) -> bool

Returns true iff the task is complete.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
