utils::SwappingSmart< T > Class Template Reference

#include <userver/utils/swappingsmart.hpp>

Detailed Description

template<typename T>
class utils::SwappingSmart< T >

Deprecated RCU-like shared_ptr cell with swap-based updates for readers.

Use a faster and more reliable rcu::Variable instead of this class!

This class helps to store pointer. Pointer stored as shared_ptr. Whet you call Get, you will get copy of this shared pointer under read lock. When you call Set pointer, it will be stored under writelock.

It works slower than SwappingPtr in 5 times, but readers will always have shared_ptr that they obtained, so it is impossible that data will be free'd.
