Struct ReadProgress 

pub struct ReadProgress { /* private fields */ }

Where a read that fetches from storage tells how much of its range is here: the count of the range’s bytes in hand, cached or received, each time it grows while the read fetches. A read this device serves alone, from its own copy or the cache, tells it nothing (§17.7).
