id summary reporter owner description type status milestone component version severity resolution keywords cc 6031 "bimap views don't contain ""key_type"" and ""mapped_type"" typedefs." Aaron Barany Matias Capeletto "The bimap views, such as ""set_of"" and ""unordered_set_of"" contain the ""value_type"" typedef for the pair type they store, but don't contain the ""key_type"" and ""mapped_type"" typedefs. These typedefs are present in all the standard mapping data structures such as std::map and boost::unordered_map. Any code that expects these typedefs to be present will work correctly when used with standard map types, but will fail when they are used with the left or right view of a bimap."
