Lightweight static Jurisdiction
information.
This crate provides interfaces to work with jurisdictions for areas around the world. Information about a jurisdiction includes
- ISO 3166 Alpha2 and Alpha3 character codes.
- ISO 3166 numeric country code.
- UN M49 region classifications.
The Jurisdiction object is a lightweight object, the size of a pointer, suitable for transfer in API surfaces throughout an ecosystem. Serialization on API boundaries may choose to employ any of the standardized classification formats.
