DIDComm FFI

DIDComm bindings based on uniffi-rs.

It's used for DIDComm Swift wrapper.

DIDComm uniffi has the following specific comparing to the core DIDComm crate:

  • Callback-based versions of pack/unpack functions and DID/Secret resolver interfaces instead of async onces. These pack/unpack functions wrap the corresponding async futures and execute them in a thread pool executor. The result is passed to a callback function.
  • The language specific bidnings are generated for the API exposed in didcomm.udl file.
