pub struct System<R, Q, F> { /* private fields */ }
Expand description

The concrete type which contains the system closure provided by the user. This struct should not be constructed directly, and instead should be created using SystemBuilder.

Implements Schedulable which is consumable by the StageExecutor, executing the closure.

Also handles caching of archetype information, as well as maintaining the provided information about what queries this system will run and, as a result, its data access.

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s. Read more

Returns the argument unchanged.

Calls U::from(self).

That is, this conversion is whatever the implementation of From<T> for U chooses to do.

Performs the conversion.
