I am trying to deserialize youtube data from the endpoint http://www.youtube.com/feeds/videos.xml?channel_id=UCHnyfMqiRRG1u-2MsSQLbXA into the Feed struct in the below Rust program. It is returning None for the media_group field in the struct Entry, even though the raw XML contains information.
NOTE :: PASTE THE http://www.youtube.com/feeds/videos.xml?channel_id=UCHnyfMqiRRG1u-2MsSQLbXA INTO A BROWSER TO VISUALIZE THE XML BETTER
