where Env: TxEnv,

Source §

type Returns = String

Source §

fn item_tx_expect(&self, prev: TxExpect) -> TxExpect

Part of the execution pre-processing, each result handler needs to produce an “expect” field, as defined in the environment. Read more

Source §

fn item_process_result(self, raw_result: &TxResponse) -> Self::Returns

The main functionality of a result handler, it either does some computation internally (e.g. execution of a lambda function), or produces a result, or both.
