Specialize std::hash for NodeId/SubmapId #1907

Open boscosiu opened 1 year ago

boscosiu commented 1 year ago

Our software uses Cartographer directly without ROS, so it utilizes the submaps API and the mapping::NodeId and mapping::SubmapId types extensively.

This change adds std::hash<T> specializations to these types so they can be used with STL unordered associative containers.
