GeoArrow Rust crates¶
A Rust implementation of the GeoArrow specification.
Crates¶
The geoarrow-rs repo is currently undergoing a large refactor from a single crate (geoarrow) to a monorepo of smaller crates, each with a more well-defined scope. As of May 2025, avoid using the geoarrow crate and instead use the newer crates with a smaller scope, like geoarrow-array and geoarrow-schema.
| Name | Description | Stability | Version | Docs |
|---|---|---|---|---|
geoarrow-array |
GeoArrow array definitions. | Pretty stable |  |
 |
geoarrow-cast |
Functions for converting from one GeoArrow geometry type to another. | Pretty stable |  |
 |
geoarrow-flatgeobuf |
Reader and writer for FlatGeobuf files to GeoArrow memory. | Somewhat stable |  |
 |
geoarrow-schema |
GeoArrow geometry type and metadata definitions. | Pretty stable |  |
 |
geoparquet |
GeoParquet reader and writer. | Unstable (a refactor is expected soon) |  |
 |
Versioning¶
These crates may diverge in versioning to allow for some sub-crates to receive breaking changes while not forcing a breaking version change to all crates. However, all crates will receive a new breaking version at least every 3 months, as the upstream arrow-rs crates currently publish a breaking version every 3 months.
