Struct diskit::std_diskit::StdDiskit

pub struct StdDiskit;

Stdlib passthrough diskit

This diskit passes all requests directly to the corresponding standard functions through. This is useful if you normally want to access the disk (then you can use this diskit), but sometimes redirect your requests somewhere else (then you should use the appropriate other diskit), or as a last element in a diskit chain (like in LogDiskit<StdDiskit>).

Thanks to special optimizations of this library this diskit is (nearly) overhead-free.
