Data.Geolocation.GEOS.Imports

Description

These are low-level FFI bindings for the Geometry Engine Open Source C API derived from geos_c.h. These enable low-level access to the native functions for parts of the C API for which high-level wrappers do not yet exist.

For the high-level API, see Data.Geolocation.GEOS.

For the monad transformer wrappers, see Data.Geolocation.GEOS.Trans.
