Struct WithResult

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

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

Value will be decoded according to the type defined in the smart contract.

Implementations

impl<T, F> WithResult<T, F>

where F: FnOnce(T),

pub fn new(f: F) -> Self

Trait Implementations

impl<Env, Original, F> RHListItem<Env, Original> for WithResult<Original, F>

where Env: TxEnv, F: FnOnce(Original),

type Returns = ()

impl<Env, Original, F> RHListItemExec<SyncCallRawResult<<Env as TxEnv>::Api>, Env, Original> for WithResult<Original, F>

where Env: TxEnv, Original: TopDecodeMulti, F: FnOnce(Original),

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.
