Trait WorldRefType 

pub trait WorldRefType<E> {
    // Required methods
    fn has_entity(&self, entity: &E) -> bool;
    fn entities(&self) -> Vec<E>;
    fn has_component<R: ReplicatedComponent>(&self, entity: &E) -> bool;

Structures that implement the WorldMutType trait will be able to be loaded into the Server at which point the Server will use this interface to keep the WorldMutType in-sync with it’s own Entities/Components

Required Methods

fn has_entity(&self, entity: &E) -> bool

check whether entity exists

fn entities(&self) -> Vec<E>

get a list of all entities in the World

fn has_component<R: ReplicatedComponent>(&self, entity: &E) -> bool

check whether entity contains component

fn has_component_of_kind( &self, entity: &E, component_kind: &ComponentKind, ) -> bool

check whether entity contains component, dynamically

fn component<'a, R: ReplicatedComponent>( &'a self, entity: &E, ) -> Option<ReplicaRefWrapper<'a, R>>

gets an entity’s component

fn component_of_kind<'a>( &'a self, entity: &E, component_kind: &ComponentKind, ) -> Option<ReplicaDynRefWrapper<'a>>

gets an entity’s component, dynamically

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.
