Struct CloneString 

pub struct CloneString<V: AsRef<str>>(pub V);

A string type which is cloned to String to use as an attribute value.

This wrapepr type exists to draw attention to the fact that using a borrowed string value requires cloning to a persistent string in the attribute state. This also permits a more efficient implementation of &'static str, which does not need this wrapper.
