# cpp_map.rs
A simple C++ std::map emulator for Rust. Probably not useful for anyone. 

I needed a data structure that could emulate a C++ std::map, and it's pointer based iterators.
More specifically it needs to emulate the insertion position hint functionality as the keys I intend to 
use are not entirely transitive. i.e., searching for insertion position from the head or tail makes a big difference.

I also needed to be able to replace the key of an already inserted item w/o altering the order. - Don't ask. 

Another gotcha is that a C++ `std::map::insert(key, value)` is a NOP if the key already exists, not even the new value will be used.

The current implementation uses a double linked Vec list, and it only supports sequential search.
