# cityjson-lib

`cityjson_lib` is the publishable CityJSON facade for Rust, plus the shared FFI
surface used by the Python and C++ bindings in this repository.

The current published surface is intentionally small:

- Rust document and feature-stream IO through `cityjson_lib::json`
- Rust workflow helpers through `cityjson_lib::ops`
- Rust summary helpers through `cityjson_lib::query`
- Python and C++ bindings over the shared FFI core

Arrow, Parquet, and wasm are not part of the current release-facing surface.

## Quick Start

```rust
use cityjson_lib::{json, query};

let model = json::from_file("amsterdam.city.json")?;
let summary = query::summary(&model);
println!("{} cityobjects", summary.cityobject_count);

let bytes = json::to_vec(&model)?;
# let _ = bytes;
# Ok::<(), cityjson_lib::Error>(())
```
