Required methods
fn get_asset(&self) -> Option<Asset>
Get the asset that has been set on the extractable object.
Returns
The asset set on self
, or None
if no asset has been set.
fn get_id(&self) -> Option<GString>
Gets the Asset:id
of some associated asset. It may be the case
that the object has no set asset, or even that such an asset does not
yet exist in the GES cache. Instead, this will return the asset
Asset:id
that is compatible with the current state of the object,
as determined by the Extractable
implementer. If it was indeed
extracted from an asset, this should return the same as its
corresponding asset Asset:id
.
Returns
The Asset:id
of some associated Asset
that is compatible with self
's current state.
fn set_asset<P: IsA<Asset>>(&self, asset: &P) -> Result<(), BoolError>
Sets the asset for this extractable object.
When an object is extracted from an asset using AssetExt::extract
its
asset will be automatically set. Note that many classes that implement
Extractable
will automatically create their objects using assets
when you call their new
methods. However, you can use this method to
associate an object with a compatible asset if it was created by other
means and does not yet have an asset. Or, for some implementations of
Extractable
, you can use this to change the asset of the given
extractable object, which will lead to a change in its state to
match the new asset Asset:id
.
asset
The asset to set
Returns
true
if asset
could be successfully set on self
.
