Crate geonative_core 

geonative-core

Core data model for geonative — a lightweight, pure-Rust geospatial library built from scratch.

This crate defines the interoperable intermediate representation that every format driver (geonative-filegdb, geonative-shapefile, geonative-geojson, geonative-geoparquet, …) reads into or writes from. The model is Simple-Features-shaped so WKB encoding, GeoJSON, Shapefile, and GeoParquet writers all become near-trivial walks over the tree.

What’s in here

• Geometry — the geometry tree (Point/Multi*/Polygon/Collection)
• Coord — a single coordinate, with optional z and m
• Value / ValueType — attribute values and their type tags
• Feature — fid + optional geometry + indexed attribute vector
• Schema / FieldDef / GeomField — layer schema description
• Crs — coordinate reference system (EPSG / WKT / PROJJSON)
• Error — common error type

Cargo features

• geo-types (off by default) — From/Into conversions between this crate’s Geometry and [geo_types::Geometry], plus Coord. Z/M is silently dropped because geo-types is 2D.

Modules

crs

Coordinate reference system. Carried through verbatim from the source so each writer can serialize it in its own preferred form.

error

Common error type. Drivers define their own dialect-specific errors and convert into this at the public-API boundary.

feature

A Feature is one row: an optional feature ID, an optional geometry, and an indexed attribute vector that parallels crate::Schema::fields.

geometry

Simple-Features geometry tree with optional Z/M ordinates.

schema

Layer schema description. Format readers populate it; format writers consult it. Fields are an ordered vector with name lookup as a secondary index — DBF, GDB, and Arrow all require defined column order.

value

Attribute values and their type tags.

wkb

OGC Simple Features Well-Known Binary (WKB) encoder + decoder for Geometry.

Constants
