§FlatCityBuf Core Library

A high-performance Rust library for encoding and decoding CityJSON data to the FlatCityBuf (FCB) binary format. FCB uses FlatBuffers for efficient serialization with support for spatial and attribute indexing.

Specifically, the following components contain code derived from FlatGeobuf:

Spatial indexing algorithms (packed R-tree implementation)
HTTP range request handling (for Rust native part)
Binary format design patterns

We extend our gratitude to the FlatGeobuf team for their excellent work on efficient geospatial binary formats, which provided the foundation for FlatCityBuf’s spatial indexing and serialization architecture.
