seastar::optimized_optional< T > Class Template Reference

Detailed Description

template<typename T>
class seastar::optimized_optional< T >

optimized_optional<> is intended mainly for use with classes that store their data externally and expect pointer to this data to be always non-null. In such case there is no real need for another flag signifying whether the optional is engaged.

#include <seastar/util/optimized_optional.hh>
