Special Functions And Pimpl Idiom

Pointer to implementation is one of the idioms in C++ which dictates that the implementation must be accessed through an indirection, which in simple words mean that we encapsulate all the member data of our class in another struct that we access via a pointer. Benefits The benefits comes in the form of lowered compilation times, easier to manage headers, the reason compile times decrease is because instead of declaring every member in a header file which than forces us to add headers as well, for example if we have members of type vector and string we will have to include their header files as well and every time we would make a change in those data member types or Let’s say we have another custom type which gets new revisions very often that would result in us recompiling the entire header for our class again. Use Pointers Like the name says we hold a pointer to implementation, the pointer can be a raw pointer, unique pointer or a shared pointer. Raw and unique pointers are most perf
