Struct Singled 

pub struct Singled<S> { /* private fields */ }

Available on crate feature client and crate feature client-pool and docsrs only.

A cached service returned from a Singleton.

Implements Service by delegating to the inner service. If poll_ready returns an error, this will clear the cache in the related Singleton.
