Type-Safe Interfaces with Modern C++ - Match – Implementation

The video tutorial explains the implementation of a match function that takes NF function objects and returns another function taking NV variance. It details the steps of building an overload set and invoking ACD visit. The tutorial covers the interface and structure of the match function, emphasizing the use of Lambda and visitor. It provides a usage example comparing traditional visitation with the match approach, highlighting the reduced boilerplate. The video concludes with an assembly comparison, showing that the match function is a zero-cost abstraction over ACD visit.
