[EMCpp]Item-23 Understand std::Move and std::Forward
· ☕ 2 min read
std::move performs an unconditional cast to an rvalue, while std::forward casts its argument to an rvalue only if that argument is bound to an rvalue.
[EMCpp]Item-22 When Using Pimple Idiom, Define Special Member Functions in the Implementation File
· ☕ 4 min read
For std::unique_ptr pImpl pointers, declare special member functions in the class header, but implement them in the implementation file.
[EMCpp]Item-21 Prefer std::make_unique and std::make_shared to Direct Use of New
· ☕ 5 min read
Compared to new, make functions eliminate source code duplication, improve exception safety, and, for std::make_shard and std::allocate_shared, generate code that’s smaller and faster.
[EMCpp]Item-20 Use Weak_ptr for Shared_ptr Like Pointers That Can Dangle
· ☕ 3 min read
Potential use cases for std::weak_ptr include caching, observer lists, and the prevention of std::shared_ptr cycles.
[EMCpp]Item-19 Use std::Shared_ptr for Shared-ownership Resource Management
· ☕ 5 min read
std::shared_ptrs offer convenience approaching that of garbage collection for the shared lifetime management of arbitrary resources.
