Trait Implementations

impl JsonRpcClientErrorExt for JsonRpcClientError

Helpers to inspect the error type from the client implementation.

fn as_error_object(&self) -> Option<&ErrorObjectOwned>

If this is a JSON-RPC error object, return a reference to it.

If submitting a transaction, these are usually pre-execution validity check failures, e.g., wrong signatures, equivocated objects, etc. Use ErrorObjectExt to extract more information from those.
