Hi, Christophe,
You shouldn't be using `~str` at all, you should use `String`. Also,
`box ""` is not a replacement for `~""`, they have different types.
The proper replacement is `String::new()` or `"".to_string()".
Your code in modern Rust will look like this:
/// Contains a list of properties. A property is a key-value pair.
pub struct Properties {
props: HashMap<String, String>
}
impl Map<String, String> for Properties {
/// Get a property value giving its name. Return None if property
does not exist.
fn find<'a>(&'a self, key: &String) -> Option<&'a String> {
self.props.find(key)
}
/// Return true if a property value exists for the specified key
fn contains_key(&self, key: &String) -> bool {
self.props.contains_key(key)
}
}
