Struct RefreshingAuthTokenProvider 

pub struct RefreshingAuthTokenProvider { /* private fields */ }

Keeps a short-lived service token warm and returns only usable tokens.

Construction starts a background refresh. Concurrent refreshes are single-flighted, and a failed early refresh leaves the last usable token in place. token returns only a token that remains usable for at least 30 seconds.
