Extra changes:
- `ABIDecoder.config` is now `pub`
- `ParamType::validate_is_decodable` now uses `DebugWithDepth` (with
depth 0 in tests and `decoder.max_depth` in use)
- `DebugWithDepth` moved to `utils` module

To help with reviewing, here are the changes added in latest merge (a7a9acc):

Extra changes:

  • ABIDecoder.config is now pub (to pass max_depth in ReceiptParser::parse)
  • ParamType::validate_is_decodable now uses DebugWithDepth, with
    depth 0 in tests (for consistent error messages) and decoder.max_depth in use (to give some insight into the type that causes the overflow)
  • DebugWithDepth moved to utils module

EDIT: DebugWithDepth now (3da2abc) lives in param_types.rs

You removed comments that are useful IMO. Also some imprecisions in the error message.
