Implementations

impl<E, Args, RetType> CallBuilder<E, Set<Call>, Args, RetType>

where E: Environment,

pub fn ref_time_limit(self, ref_time_limit: Gas) -> Self

Sets the ref_time_limit part of the weight limit for the current cross-contract call.

ref_time refers to the amount of computational time that can be used for execution, in picoseconds. You can find more info here.

pub fn proof_size_limit(self, proof_size_limit: Gas) -> Self

Sets the proof_size_limit part of the weight limit for the current cross-contract call.

proof_size refers to the amount of storage in bytes that a transaction is allowed to read. You can find more info here.

Note

This limit is only relevant for parachains, not for standalone chains which do not require sending a Proof-of-validity to the relay chain.

pub fn storage_deposit_limit(self, storage_deposit_limit: U256) -> Self

Sets the storage_deposit_limit for the current cross-contract call.

The storage_deposit_limit specifies the amount of user funds that can be charged for creating storage. You can find more info here.

pub fn transferred_value(self, transferred_value: U256) -> Self

Sets the transferred_value for the current cross-contract call.

This value specifies the amount of user funds that are transferred to the other contract with this call.

pub fn call_flags(self, call_flags: CallFlags) -> Self

Sets the call_flags for the current cross-contract call.

These flags are used to change the behavior of the contract call.

impl<E, Args, RetType> CallBuilder<E, Set<Call>, Set<ExecutionInput<Args>>, Set<ReturnType<RetType>>>

where E: Environment,

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

Finalizes the call builder to call a function.

where E: Environment,

pub fn invoke(self)

Invokes the cross-chain function call.

Panics

This method panics if it encounters an ink::env::Error or an [ink::primitives::LangError][ink_primitives::LangError]. If you want to handle those use the try_invoke method instead.

pub fn try_invoke(self) -> Result<MessageResult<()>, Error>

Invokes the cross-chain function call.

Note

On failure this returns an outer ink::env::Error or inner [ink::primitives::LangError][ink_primitives::LangError], both of which can be handled by the caller.

impl<E, Args, R> CallBuilder<E, Set<Call>, Set<ExecutionInput<Args>>, Set<ReturnType<R>>>

where E: Environment, Args: Encode, R: Decode,

pub fn invoke(self) -> R

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

Panics

This method panics if it encounters an ink::env::Error or an [ink::primitives::LangError][ink_primitives::LangError]. If you want to handle those use the try_invoke method instead.

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

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

Note

On failure this returns an outer ink::env::Error or inner [ink::primitives::LangError][ink_primitives::LangError], both of which can be handled by the caller.

impl<E, Args, RetType> CallBuilder<E, Set<DelegateCall>, Set<ExecutionInput<Args>>, Set<ReturnType<RetType>>>

where E: Environment,

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

where E: Environment,

pub fn params(self) -> CallParams<E, DelegateCall, EmptyArgumentList, ()>

impl<E> CallBuilder<E, Set<DelegateCall>, Unset<ExecutionInput<EmptyArgumentList>>, Unset<ReturnType<()>>>

where E: Environment,

pub fn invoke(self)

Invokes the cross-chain function call using Delegate Call semantics.

Panics

This method panics if it encounters an ink::env::Error If you want to handle those use the try_invoke method instead.

pub fn try_invoke(self) -> Result<MessageResult<()>, Error>

Invokes the cross-chain function call using Delegate Call semantics.

Note

On failure this an ink::env::Error which can be handled by the caller.

impl<E, Args, R> CallBuilder<E, Set<DelegateCall>, Set<ExecutionInput<Args>>, Set<ReturnType<R>>>

where E: Environment, Args: Encode, R: Decode,

pub fn invoke(self) -> R

Invokes the cross-chain function call using Delegate Call semantics and returns the result.

Panics

This method panics if it encounters an ink::env::Error or an [ink::primitives::LangError][ink_primitives::LangError]. If you want to handle those use the try_invoke method instead.

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

Invokes the cross-chain function call using Delegate Call semantics and returns the result.

Note

On failure this returns an outer ink::env::Error or inner [ink::primitives::LangError][ink_primitives::LangError], both of which can be handled by the caller.

impl<E, CallType, Args, RetType> CallBuilder<E, Unset<CallType>, Args, RetType>
