[−][src]Struct feed_rs::model::Feed
Combined model for a syndication feed (i.e. RSS1, RSS 2, Atom, JSON Feed)
The model is based on the Atom standard as a start with RSS1+2 mapped on to it e.g.
- Atom
- Feed -> Feed
- Entry -> Entry
- RSS 1 + 2
- Channel -> Feed
- Item -> Entry
Certain elements are not mapped given their limited utility:
- RSS 2:
- channel - docs (pointer to the spec), cloud (for callbacks), textInput (text box e.g. for search)
- item - comments (link to comments on the article), source (pointer to the channel, but our data model links items to a channel)
- RSS 1:
- channel - rdf:about attribute (pointer to feed), textinput (text box e.g. for search)
