Required methods

fn extract(&self) -> Result<Option<Extractable>, Error>[−]

Extracts a new gobject::Object from asset. The type of the object is defined by the extractable-type of asset, you can check what type will be extracted from asset using AssetExt::get_extractable_type

Returns

A newly created Extractable

fn get_error(&self) -> Option<Error>[−]

Returns

The glib::Error of the asset or None if the asset was loaded without issue

fn get_extractable_type(&self) -> Type[−]

Gets the type of object that can be extracted from self

Returns

the type of object that can be extracted from self

fn get_id(&self) -> Option<GString>[−]

Gets the ID of a Asset

Returns

The ID of self

fn get_proxy(&self) -> Option<Asset>[−]

Returns

The proxy in use for self

fn get_proxy_target(&self) -> Option<Asset>[−]

Returns

The Asset that is proxied by self

fn list_proxies(&self) -> Vec<Asset>[−]

Returns

The list of proxies self has. Note that the default asset to be used is always the first in that list.

fn set_proxy<P: IsA<Asset>>(&self, proxy: Option<&P>) -> Result<(), BoolError>[−]

A proxying asset is an asset that can substitue the real self. For example if you have a full HD UriClipAsset you might want to set a lower resolution (HD version of the same file) as proxy. Note that when an asset is proxied, calling Asset::request will actually return the proxy asset.

proxy

The Asset that should be used as default proxy for self or None if you want to use the currently set proxy. Note that an asset can proxy one and only one other asset.

Returns

true if proxy has been set on self, false otherwise.

fn unproxy<P: IsA<Asset>>(&self, proxy: &P) -> Result<(), BoolError>[−]

Removes proxy from the list of known proxies for self. If proxy was the current proxy for self, stop using it.

proxy

The Asset to stop considering as a proxy for self

Returns

true if proxy was a known proxy for self, false otherwise.

fn set_property_proxy_target<P: IsA<Asset> + SetValueOptional>(
    &self,
    proxy_target: Option<&P>
)

fn connect_property_proxy_notify<F: Fn(&Self) + 'static>(
    &self,
    f: F
) -> SignalHandlerId

fn connect_property_proxy_target_notify<F: Fn(&Self) + 'static>(
    &self,
    f: F
) -> SignalHandlerId
