Trait EntityStore 

pub trait EntityStore {
    // Required methods
    fn id(&self) -> WorldId;
    fn entry_ref(
        &self,
        entity: Entity,
    ) -> Result<EntryRef<'_>, EntityAccessError>;
    fn entry_mut(
        &mut self,
        entity: Entity,
    ) -> Result<EntryMut<'_>, EntityAccessError>;
    fn get_component_storage<V>(
        &self,
    ) -> Result<StorageAccessor<'_>, EntityAccessError>
       where V: for<'b> View<'b>;
}

The EntityStore trait abstracts access to entity data as required by queries for both World and SubWorld

Required Methods

fn id(&self) -> WorldId

Returns the world’s unique ID.

fn entry_ref(&self, entity: Entity) -> Result<EntryRef<'_>, EntityAccessError>

Returns an entity entry which can be used to access entity metadata and components.

fn entry_mut( &mut self, entity: Entity, ) -> Result<EntryMut<'_>, EntityAccessError>

Returns a mutable entity entry which can be used to access entity metadata and components.

fn get_component_storage<V>( &self, ) -> Result<StorageAccessor<'_>, EntityAccessError>

where V: for<'b> View<'b>,

Returns a component storage accessor for component types declared in the specified View.

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.
