Expand description

An “untyped” / “generic-less” Asset identifier that behaves much like AssetId, but stores the Asset type information at runtime instead of compile-time. This increases the size of the type, but it enables storing asset ids across asset types together and enables comparisons between them.

Variants§

§

Index

Fields

§type_id: TypeId

A small / efficient runtime identifier that can be used to efficiently look up an asset stored in Assets. This is the “default” identifier used for assets. The alternative(s) (ex: UntypedAssetId::Uuid) will only be used if assets are explicitly registered that way.

§

Uuid

Fields

§type_id: TypeId
§uuid: Uuid

A stable-across-runs / const asset identifier. This will only be used if an asset is explicitly registered in Assets with one.

Implementations§

source§

impl UntypedAssetId

source

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

Converts this to a “typed” AssetId without checking the stored type to see if it matches the target A Asset type. This should only be called if you are absolutely certain the asset type matches the stored type. And even then, you should consider using UntypedAssetId::typed_debug_checked instead.

source

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

Converts this to a “typed” AssetId. When compiled in debug-mode it will check to see if the stored type matches the target A Asset type. When compiled in release-mode, this check will be skipped.

Panics

Panics if compiled in debug mode and the TypeId of A does not match the stored TypeId.

source

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

Converts this to a “typed” AssetId.

Panics

Panics if the TypeId of A does not match the stored type id.

source

pub fn try_typed<A: Asset>( self ) -> Result<AssetId<A>, UntypedAssetIdConversionError>

Try to convert this to a “typed” AssetId.

source

pub fn type_id(&self) -> TypeId

Returns the stored TypeId of the referenced Asset.
