Here is a sample snippet of the contract generated by the Rust consumer. Note the additional

path

entry in the

request.metadata

(required for establishing the initial connection):

...
   "request": {
        "contents": {
            ...
        "metadata": {
          "contentType": "application/json",
          "path": "/jsonrpc"
        }
   ...

The consumer achieves this by making use of the

contents_from

, along the lines of:

let mock_server = pact_builder
        .synchronous_message_interaction("sync message example", |mut i| async move {
            i.contents_from(json!({
                "pact:content-type": "application/json",
                "request": {
                    "query": "matching(equalTo, 'getTheData')"
                },
                "requestMetadata": {
                    "path": "/jsonrpc"
                    },
                },
                "response": [{
                    "data": "matching(equalTo, 'The data')"
                }]
            }))
    ...

For the FFI consumer I am using

pactffi_new_sync_message_interaction

and the

pactffi_

methods that work with

InteractionHandle

. Ideally I would like to achieve the same thing using the FFI, but I could not identify an API that would allow this. Can someone advise if it is possible to achieve this using the current FFI API? Or is this something that is missing and needs to be added?
