pub enum UntypedHandle {
    Strong(Arc<StrongHandle>),
    Weak(UntypedAssetId),
}
Expand description

An untyped variant of Handle, which internally stores the Asset type information at runtime as a TypeId instead of encoding it in the compile-time type. This allows handles across Asset types to be stored together and compared.

See Handle for more information.

Implementations§

source§

impl UntypedHandle

source

pub fn id(&self) -> UntypedAssetId

Returns the UntypedAssetId for the referenced asset.

source

pub fn path(&self) -> Option<&AssetPath<'static>>

Returns the path if this is (1) a strong handle and (2) the asset has a path

source

pub fn clone_weak(&self) -> UntypedHandle

Creates an UntypedHandle::Weak clone of this UntypedHandle, which will not keep the referenced Asset alive.

source

pub fn type_id(&self) -> TypeId

Returns the TypeId of the referenced Asset.

source

pub fn typed_unchecked<A: Asset>(self) -> Handle<A>

Converts to a typed Handle. This will not check if the target Handle type matches.

source

pub fn typed_debug_checked<A: Asset>(self) -> Handle<A>

Converts to a typed Handle. This will check the type when compiled with debug asserts, but it will not check if the target Handle type matches in release builds. Use this as an optimization when you want some degree of validation at dev-time, but you are also very certain that the type actually matches.

source

pub fn typed<A: Asset>(self) -> Handle<A>

Converts to a typed Handle. This will panic if the internal TypeId does not match the given asset type A

source

pub fn try_typed<A: Asset>( self ) -> Result<Handle<A>, UntypedAssetConversionError>

Converts to a typed Handle. This will panic if the internal TypeId does not match the given asset type A

source

pub fn meta_transform(&self) -> Option<&MetaTransform>

The “meta transform” for the strong handle. This will only be Some if the handle is strong and there is a meta transform associated with it.
