Struct bevy_internal::ecs::component::ComponentDescriptor

pub struct ComponentDescriptor { /* private fields */ }

A value describing a component or resource, which may or may not correspond to a Rust type.

Implementations

impl ComponentDescriptor

pub fn new<T>() -> ComponentDescriptor

where T: Component,

Create a new ComponentDescriptor for the type T.

pub unsafe fn new_with_layout( name: impl Into<Cow<'static, str>>, storage_type: StorageType, layout: Layout, drop: Option<for<'a> unsafe fn(_: OwningPtr<'a>)> ) -> ComponentDescriptor

Create a new ComponentDescriptor.

Safety

• the drop fn must be usable on a pointer with a value of the layout layout
• the component type must be safe to access from any thread (Send + Sync in rust terms)

pub fn new_resource<T>() -> ComponentDescriptor

where T: Resource,

Create a new ComponentDescriptor for a resource.

The StorageType for resources is always TableStorage.

pub fn storage_type(&self) -> StorageType

Returns a value indicating the storage strategy for the current component.

pub fn type_id(&self) -> Option<TypeId>

Returns the TypeId of the underlying component type. Returns None if the component does not correspond to a Rust type.

pub fn name(&self) -> &str

Returns the name of the current component.
