Is the contract deployed correctly under incentive_layer_address? Can you run the node with RPC tracing to see what exactly is returned by the server?
You can also set up env_logger in your program and run with RUST_LOG="web3=trace" to see more details about incoming responses.

I'm deploying the contract with truffle and then writing the address to a json file. Seems to be working correctly when using interacting with web3js. Am I doing anything incorrectly in this line?
let incentive_layer_contract = Contract::from_json(web3.eth(), incentive_layer_address, il.as_bytes()).unwrap();Here is the output from the log:

I wasn't able to look at the output because it breaks on the decoding part.

Logs are not that helpful, they don't contain raw responses from the client. Could you run the client with response logging?

Ran parity with --logging=rpc=trace flag
Got this output:
2018-03-12 11:33:56 TRACE rpc Request: {"jsonrpc":"2.0","method":"eth_call","params":[{"data":"0xe1254fba00000000000000000000000000a329c0648769a73afac7f9381e08fb43dbea72","to":"0x2230786463623339333431663666623836316633"},"latest"],"id":3}.

The response result is definitely not correct

Perhaps the contract is not yet deployed? Can you check eth_getCode("0x2230786463623339333431663666623836316633")?

Yes the code is there after checking.
I haven't had this issue before, but one thing I am doing differently is using the truffle artifacts. It is possible that the format for the abi is not the same as what is expected by this library, however this would surprise me since abi is a standard format.
Another difference is that I am not deploying the contract with rust-web3 but rather with truffle.
I'm running parity and then deploying the contracts with truffle migrate --reset, the deployment script writes the address to the addresses.json file which I am using for the client code.
Here is the entire repo/branch for reference: https://github.com/TrueBitFoundation/incentive-layer/tree/rust_client

There has been many changes in recent versions of ethereum-types that might affect Ser/De of the structs. Please reopen if the issue persists.
