Trait StorageMutExt 

pub trait StorageMutExt<C: Mirrored>: StorageExt<C> {
    // Required methods
    fn modify(
        &mut self,
        entity: Entity,
    ) -> Option<(&mut C, &mut EventChannel<C::Event>)>;
    fn event_channel(&mut self) -> &mut EventChannel<C::Event>;

    // Provided method
    fn register_reader(&mut self) -> ReaderId<C::Event> { ... }
}

Extension methods for Storage to help read events from MirroredStorage.

Required Methods

fn modify( &mut self, entity: Entity, ) -> Option<(&mut C, &mut EventChannel<C::Event>)>

Get a mutable reference to the component and the event channel for update events.

fn event_channel(&mut self) -> &mut EventChannel<C::Event>

Get a mutable reference to the event channel for update events.

Provided Methods

fn register_reader(&mut self) -> ReaderId<C::Event>

Register a new reader of insertion and removal events.

Dyn Compatibility

This trait is dyn compatible.

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