Type Alias metrics::SharedString

pub type SharedString = Cow<'static, str>;

An allocation-optimized string.

We specify SharedString to attempt to get the best of both worlds: flexibility to provide a static or dynamic (owned) string, while retaining the performance benefits of being able to take ownership of owned strings and borrows of completely static strings.

SharedString can be converted to from either &'static str or String, with a method, const_str, from constructing SharedString from &'static str in a const fashion.
