Expand description
A reference counted string that acts like a regular str slice, hiding the
fact that it is wrapped in Rc.
§Example
use rcstr::RcStr;
use std::collections::HashSet;
let mut map: HashSet<RcStr> = HashSet::new();
map.insert(RcStr::new("foo"));
assert!(map.contains("foo"));
assert!(map.contains(&RcStr::new("foo")));
assert!(!map.contains("bar"));
