Struct ink_env::call::CallBuilder

pub struct CallBuilder<E, Callee, GasLimit, TransferredValue, Args, RetType> where
    E: Environment,  { /* fields omitted */ }

Builds up a cross contract call.

Implementations

impl<E, GasLimit, TransferredValue, Args, RetType> CallBuilder<E, Unset<E::AccountId>, GasLimit, TransferredValue, Args, RetType> where
    E: Environment, 

pub fn callee(
    self,
    callee: E::AccountId
) -> CallBuilder<E, Set<E::AccountId>, GasLimit, TransferredValue, Args, RetType>

Sets the called smart contract instance account ID to the given value.

impl<E, Callee, TransferredValue, Args, RetType> CallBuilder<E, Callee, Unset<u64>, TransferredValue, Args, RetType> where
    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.

impl<E, Callee, GasLimit, TransferredValue, RetType> CallBuilder<E, Callee, GasLimit, TransferredValue, Unset<ExecutionInput<EmptyArgumentList>>, RetType> where
    E: Environment, 

pub fn exec_input<Args>(
    self,
    exec_input: ExecutionInput<Args>
) -> CallBuilder<E, Callee, GasLimit, TransferredValue, Set<ExecutionInput<Args>>, RetType>

Sets the execution input to the given value.

impl<E, GasLimit, TransferredValue, Args, RetType> CallBuilder<E, Set<E::AccountId>, GasLimit, TransferredValue, Set<ExecutionInput<Args>>, Set<RetType>> where
    E: Environment,
    GasLimit: Unwrap<Output = u64>,
    TransferredValue: Unwrap<Output = E::Balance>, 

pub fn params(self) -> CallParams<E, Args, RetType>

Finalizes the call builder to call a function.

impl<E, GasLimit, TransferredValue, Args> CallBuilder<E, Set<E::AccountId>, GasLimit, TransferredValue, Set<ExecutionInput<Args>>, Set<()>> where
    E: Environment,
    GasLimit: Unwrap<Output = u64>,

    TransferredValue: Unwrap<Output = E::Balance>, 

pub fn fire(self) -> Result<(), Error>

Invokes the cross-chain function call.

impl<E, GasLimit, TransferredValue, Args, R> CallBuilder<E, Set<E::AccountId>, GasLimit, TransferredValue, Set<ExecutionInput<Args>>, Set<ReturnType<R>>> where
    E: Environment,
    GasLimit: Unwrap<Output = u64>,
    Args: Encode,
    R: Decode,
    TransferredValue: Unwrap<Output = E::Balance>, 

pub fn fire(self) -> Result<R, Error>

Invokes the cross-chain function call and returns the result.
