go-geoindex

Benchmarks show operations in microseconds, handling up to 100K+ points efficiently, as evidenced by the provided performance data in the README.

Allows custom point types by implementing a simple interface (Lat, Lon, Id methods), making it easy to integrate with existing Go structs like Driver.

Supports points, counts, and clustering indexes with optional expiration, enabling real-time use cases such as expiring driver locations or clustered maps.

Offers a minimal, idiomatic Go API with clear methods like Add, Remove, KNearest, and Range, as shown in the code examples.
