class EventFilter a  where

Members

• eventFilter :: Proxy a -> Address -> Filter

  Event filter structure used by low-level subscription methods

event :: forall ni i a e. DecodeEvent i ni a => Filter -> (a -> ReaderT Change (Web3 e) EventAction) -> Web3 e Unit

run event' one block at a time.

event' :: forall ni i a e. DecodeEvent i ni a => Filter -> Int -> (a -> ReaderT Change (Web3 e) EventAction) -> Web3 e Unit

Takes a Filter and a handler, as well as a windowSize. It runs the handler over the eventLogs using reduceEventStream. If no TerminateEvent is thrown, it then transitions to polling.

class CallMethod (selector :: Symbol) a b  where

Members

• call :: forall e. IsSymbol selector => TransactionOptions NoPay -> ChainCursor -> Tagged (SProxy selector) a -> Web3 e (Either CallError b)

  Constant call given contract 'Address' in mode and given input data

Instances

• (Generic a arep, GenericABIEncode arep, Generic b brep, GenericABIDecode brep) => CallMethod s a b

class TxMethod (selector :: Symbol) a  where

Class paramaterized by values which are ABIEncodable, allowing the templating of of a transaction with this value as the payload.

Members

• sendTx :: forall u e. EtherUnit (Value u) => IsSymbol selector => TransactionOptions u -> Tagged (SProxy selector) a -> Web3 e HexString

  Send a transaction for given contract 'Address', value and input data

Instances

• (Generic a rep, GenericABIEncode rep) => TxMethod s a
