geocoordinates (language bindings)
UniFFI bindings for the
geocoordinates geospatial library —
China datums (GCJ-02 / BD-09), geodetic transforms.
A deliberately curated, flattened subset of the Rust API is exposed across the FFI
boundary to Python, Kotlin, Swift, and TypeScript (Java consumes the Kotlin/JVM
artifact). Generics, traits, operator overloads, and From/TryFrom conversions do
not cross FFI, so they are re-expressed as flat records and free functions; approximate
inverses keep their _fast / _refined names and carry an explicit max_error_m.
Surface
WGS-84 ↔ GCJ-02 ↔ BD-09 conversions (exact forward, approximate inverse with error
bounds), Baidu Web Mercator, out_of_china, and haversine distance.
import geocoordinates_ffi as gc
gcj = gc.wgs84_to_gcj02(gc.Wgs84(lat=39.915, lon=116.404))
wgs = gc.gcj02_to_wgs84_refined(gcj) # approximate inverse
print(wgs.lat, wgs.lon, "±", wgs.max_error_m, "m")
The WebAssembly/TypeScript bindings live in web/.
