Trait for allowing function to work on both World and SubWorld

Required Methods

fn to_ref<T: ComponentBorrow + Subset>(&self) -> SubWorldRef<'_, T>

Convert the subworld into another holding an internal reference to the original world.

fn try_query<Q: Query + Subset>(&self) -> Result<QueryBorrow<'_, Q>>

Queries the world

fn try_query_one<Q: Query + Subset>( &self, entity: Entity ) -> Result<QueryOne<'_, Q>>

Queries the world for a specific entity

fn try_get<C: Component>(&self, entity: Entity) -> Result<Ref<'_, C>>

Get a single component for an entity Returns the contextual result since hecs-schedule is required to be imported anyway

fn try_get_mut<C: Component>(&self, entity: Entity) -> Result<RefMut<'_, C>>

Get a single component for an entity Returns the contextual result since hecs-schedule is required to be imported anyway

fn reserve(&self) -> Entity

Reserve an entity

Provided Methods

fn to_empty(&self) -> EmptyWorld<'_>

Transform this into a subworld which borrows no components. This is useful for concurrent access of entities.

Implementations on Foreign Types

impl GenericWorld for World
