Utilities to call or instantiate contracts on the chain.

Modules§

state: Type states that tell what state of a instantiation argument has not yet been set properly for a valid construction.
utils: Utility types for the cross-contract calling API.

Call: The default call type for cross-contract calls, for calling into the latest call host function. This adds the additional weight limit parameter proof_size_limit as well as storage_deposit_limit.
CallBuilder: Builds up a cross contract call.
CallParams: The final parameters to the cross-contract call.
CreateBuilder: Builds up contract instantiations.
CreateParams: Builds up contract instantiations.
DelegateCall: The delegatecall call type. Performs a call with the given code hash.
Execution: The input data and the expected return type of a contract execution.
ExecutionInput: The input data for a smart contract execution.
LimitParamsV2: Defines the limit params for the new ext::instantiate host function. todo: rename
Selector: The function selector.

ConstructorReturnType: Represents any type that can be returned from an ink! constructor. The following contract implements the four different return type signatures implementing this trait:
Executor: Implemented in different environments to perform contract execution.
FromAddr: Contracts that can be constructed from an AccountId.

build_call: Returns a new CallBuilder to build up the parameters to a cross-contract call that uses the ink! ABI (SCALE Encoding).
build_call_solidity: Returns a new CallBuilder to build up the parameters to a cross-contract call that uses Solidity ABI Encoding. See build_call for more details on usage.
build_create: Returns a new CreateBuilder to build up the parameters to a cross-contract instantiation for a contract that uses the ink! ABI (SCALE Encoding).
build_create_solidity: Returns a new CreateBuilder to build up the parameters to a cross-contract instantiation for an ink! contract that uses Solidity ABI Encoding. See build_create for more details on usage.
