/// the HTTP request to GET `http://example.com:5984/db`.
///
/// Database names may be converted to and from strings. They are never
/// percent-encoded.
///
/// Although the `DatabaseName` type implements the `Ord` and `PartialOrd`
/// traits, it provides no guarantees how that ordering is defined and may
/// change the definition between any two releases of the couchdb crate. That
/// is, for two `DatabaseName` values `a` and `b`, the expression `a < b` may
/// hold true now but not in a subsequent release. Consequently, applications
/// must not rely upon any particular ordering definition.
