Struct Instrumented 

pub struct Instrumented<T> { /* private fields */ }

A stop policy or progress sink whose calls are recorded in a span.

It is 'static whenever the wrapped value is, so it can go wherever the original went: into a codec context, a spawned thread, or an Arc<dyn Stop>. may_stop and may_report always return true, so callers that skip no-op policies still make the calls being measured.
