About:
robin-map is a C++ implementation of a hash map and hash set using Robin Hood hashing. It provides a high-performance, header-only alternative to standard library containers with lower memory overhead and faster lookups. The library focuses on speed and efficiency for performance-critical applications.
Key Features:
  • Header-only library requiring no compilation
  • Robin Hood hashing for high performance
  • Lower memory usage than std::unordered_map
  • Compatible with C++11 and later standards
  • Drop-in replacement for standard containers
Use Cases:
  • High-performance computing requiring fast hash table operations
  • Game development for efficient data structures
  • Systems programming where memory efficiency is critical
  • Real-time applications needing predictable performance
Alternatives:
  • std::unordered_map – Standard library container with higher memory overhead and slower average performance
  • absl::flat_hash_map – Google's alternative with similar performance but larger dependency footprint
