The API used to dry-run contract interactions.

Provided Methods

fn call( &self, __runtime_api_at_param__: <Block as BlockT>::Hash, origin: AccountId, dest: AccountId, value: Balance, gas_limit: Option<Weight>, storage_deposit_limit: Option<Balance>, input_data: Vec<u8>, ) -> Result<ContractExecResult<Balance, EventRecord>, ApiError>

Perform a call from a specified account to a given contract.

See crate::Pallet::bare_call.

fn instantiate( &self, __runtime_api_at_param__: <Block as BlockT>::Hash, origin: AccountId, value: Balance, gas_limit: Option<Weight>, storage_deposit_limit: Option<Balance>, code: Code<Hash>, data: Vec<u8>, salt: Vec<u8>, ) -> Result<ContractInstantiateResult<AccountId, Balance, EventRecord>, ApiError>

Instantiate a new contract.

See [crate::Pallet::bare_instantiate].

fn upload_code( &self, __runtime_api_at_param__: <Block as BlockT>::Hash, origin: AccountId, code: Vec<u8>, storage_deposit_limit: Option<Balance>, determinism: Determinism, ) -> Result<CodeUploadResult<Hash, Balance>, ApiError>

Upload new code without instantiating a contract from it.

See crate::Pallet::bare_upload_code.

fn get_storage( &self, __runtime_api_at_param__: <Block as BlockT>::Hash, address: AccountId, key: Vec<u8>, ) -> Result<GetStorageResult, ApiError>

Query a given storage key in a given contract.

Returns Ok(Some(Vec<u8>)) if the storage value exists under the given key in the specified account and Ok(None) if it doesn’t. If the account specified by the address doesn’t exist, or doesn’t have a contract then Err is returned.
