Struct WithResultAs

pub struct WithResultAs<T, F>
where
    F: FnOnce(T),
{
    pub f: F,
    /* private fields */
}

Defines a lambda function to be called on the decoded result.

Value will be converted to type T, which should be compatible with the original type.

Fields

f: F

fn item_process_result( self, raw_result: &SyncCallRawResult<Env::Api>, ) -> 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.

fn item_tx_expect(&self, prev: Env::RHExpect) -> Env::RHExpect

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