IntrusivePtr

#include <icy/memory.h>

template<typename T>
class IntrusivePtr

Defined in src/base/include/icy/memory.h:90

Intrusive smart pointer for RefCounted objects.

Like std::shared_ptr but with zero allocation overhead:

No separate control block (refcount is embedded in the object)
Non-atomic refcount (safe for single-threaded libuv loops)
Same API as shared_ptr for easy migration
