Struct bevy::asset::HandleUntyped

pub struct HandleUntyped { /* private fields */ }
Expand description

A non-generic version of Handle.

This allows handles to be mingled in a cross asset context. For example, storing Handle<A> and Handle<B> in the same HashSet<HandleUntyped>.

To convert back to a typed handle, use the typed method.

Implementations§

§

impl HandleUntyped

pub const fn weak_from_u64(uuid: Uuid, id: u64) -> HandleUntyped

Creates a weak untyped handle with an arbitrary id.

pub fn weak(id: HandleId) -> HandleUntyped

Create a weak, untyped handle into an Asset identified by id.

pub fn id(&self) -> HandleId

The ID of the asset.

pub fn clone_weak(&self) -> HandleUntyped

Creates a weak copy of this handle.

pub fn is_weak(&self) -> bool

Returns true if this is a weak handle.

pub fn is_strong(&self) -> bool

Returns true if this is a strong handle.

pub fn typed_weak<T>(&self) -> Handle<T>where T: Asset,

Create a weak typed Handle from this handle.

If this handle is strong and dropped, there is no guarantee that the asset will still be available (if only the returned handle is kept)

pub fn typed<T>(self) -> Handle<T>where T: Asset,

Converts this handle into a typed Handle of an Asset T.

The new handle will maintain the Strong or Weak status of the current handle.

Panics

Will panic if type T doesn’t match this handle’s actual asset type.
