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
