pub enum ResourceNotUnloadableError {
    InUse,

}

Error returned when trying to unload and Resource and it fails.

Variants

InUse

The resource can not be unloaded because its in use.

The resource can not be unloaded because it doesn't has a source.

Which means if we would unload it we could not reload it. Note that unloading is just for thinks like caching, it doesn't affect the deletion/dropping of Resource instances.
