Function dbus::arg::prop_cast

pub fn prop_cast<'a, T: 'static>(map: &'a PropMap, key: &str) -> Option<&'a T>

Descend into a hashmap returned by e g “Properties::get_all” to retrieve the value of a property.

Shortcut for get + cast. Returns None both if the property does not exist, or if it was of a different type. See the argument guide’s reference section for which types you can cast to.
