pub fn call_flags(
    self,
    call_flags: CallFlags
) -> CallBuilder<E, Callee, GasLimit, TransferredValue, Args, RetType>

The flags used to change the behavior of the contract call.

    E: Environment, 

pub fn gas_limit(
    self,
    gas_limit: u64
) -> CallBuilder<E, Callee, Set<u64>, TransferredValue, Args, RetType>

Sets the maximum allowed gas costs for the call.

impl<E, Callee, GasLimit, Args, RetType> CallBuilder<E, Callee, GasLimit, Unset<E::Balance>, Args, RetType> where
    E: Environment, 

pub fn transferred_value(
    self,
    transferred_value: E::Balance
) -> CallBuilder<E, Callee, GasLimit, Set<E::Balance>, Args, RetType>

Sets the value transferred upon the execution of the call.

impl<E, Callee, GasLimit, TransferredValue, Args> CallBuilder<E, Callee, GasLimit, TransferredValue, Args, Unset<ReturnType<()>>> where
    E: Environment, 

pub fn returns<R>(
    self
) -> CallBuilder<E, Callee, GasLimit, TransferredValue, Args, Set<R>> where
    R: IndicateReturnType, 

Sets the type of the returned value upon the execution of the call.

Note

Either use .returns::<()> to signal that the call does not return a value or use .returns::<ReturnType<T>> to signal that the call returns a value of type T.

) -> CallBuilder<E, Callee, GasLimit, TransferredValue, Set<ExecutionInput<Args>>, RetType>

Sets the execution input to the given value.
