11/// - `content:encoded` → adds to entry.content with type "text/html"
12use crate::types::{Content, Entry};

14/// Content namespace URI
15pub const CONTENT_NAMESPACE: &str = "http://purl.org/rss/1.0/modules/content/";
16
17/// Handle Content namespace element at entry level
18///
19/// # Arguments
20///
21/// * `element` - Local name of the element (without namespace prefix)
22/// * `text` - Text content of the element
23/// * `entry` - Entry to update
