Macros

df_result

This macro is a helpful conversion utility to convert from an abi_stable::RResult to a DataFusion result.

rresult

This macro is a helpful conversion utility to convert from a DataFusion Result to an abi_stable::RResult

rresult_return

This macro is a helpful conversion utility to convert from a DataFusion Result to an abi_stable::RResult and to also call return when it is an error. Since you cannot use ? on an RResult, this is designed to mimic the pattern.

Functions

get_library_marker_id

This utility is used to determine if two FFI structs are within the same library. It is possible that the interplay between foreign and local functions calls create one FFI struct that references another. It is helpful to determine if a foreign struct in the same library or called from a different one. If we are in the same library, then we can access the underlying types directly.

version

Returns the major version of the FFI implementation. If the API evolves, we use the major version to identify compatibility over the unsafe boundary. This call is intended to be used by implementers to validate they have compatible libraries.
