ContractCallLocal

ContractCallLocalQuery

Call a function of the given smart contract instance, giving it functionParameters as its inputs. It will consume the entire given amount of gas.

Field	Type	Description
`header`	QueryHeader	Standard info sent from client to node, including the signed payment, and what kind of response is requested (cost, state proof, both, or neither). The payment must cover the fees and all of the gas offered.
`contractID`	ContractID	The contract to make a static call against
`gas`	int64	The amount of gas to use for the call. All of the gas offered will be charged for.
`functionParameters`	bytes	Which function to call, and the parameters to pass to the function
`maxResultSize`	int64	Max number of bytes that the result might include. The run will fail if it would have returned more than this number of bytes. [deprecated 0.20.0]

ContractCallLocalResponse

Response when the client sends the node ContractCallLocalQuery

Field	Type	Description
`header`	ResponseHeader	standard response from node to client, including the requested fields: cost, or state proof, or both, or neither
`functionResult`	ContractFunctionResult	the value returned by the function (if it completed and didn’t fail)

ContractFunctionResult

The result returned by a call to a smart contract function. This is part of the response to a ContractCallLocal query, and is in the record for a ContractCall or ContractCreateInstance transaction. The ContractCreateInstance transaction record has the results of the call to the constructor.

Field	Type	Description
`contractID`	ContractID	The smart contract instance whose function was called
`contractCallResult`	bytes	The result returned by the function
`errorMessage`	string	The message in case there was an error during smart contract execution
`bloom`	bytes	Bloom filter for record
`gasUsed`	uint64	Units of gas used to execute contract
`logInfo`	ContractLoginfo	The log info for events returned by the function
`createdContractIDs`	repeated ContractID	The list of smart contracts that were created by the function call [deprecated]
`stateChanges`	repeated ContractStateChange	The list of state reads and changes caused by this function call
`evm_address`	bytes	The 20-byte EVM address of the contract to call. Only populated after release 0.23, where each created contract will have its own record. There will be seperate chld record for each created contract. Every contract has an EVM address determined by its shard.realm.num id. This address is as follows: The first 4 bytes are the big-endian representation of the shard. The next 8 bytes are the big-endian representation of the realm. The final 8 bytes are the big-endian representation of the number. Contracts created via CREATE2 have an additional, primary address that is derived from the EIP-1014 specification, and does not have a simple relation to a shard.realm.num id. (Please do note that CREATE2 contracts can also be referenced by the three-part EVM address described above.)
`gas`	int64	The amount of gas available for the call, aka the gasLimit. This field should only be populated when the paired TransactionBody in the record stream is not a ContractCreateTransactionBody or a ContractCallTransactionBody.
`amount`	int64	Number of tinybars sent (the function must be payable if this is nonzero). This field should only be populated when the paired TransactionBody in the record stream is not a ContractCreateTransactionBody or a ContractCallTransactionBody.
`functionParameters`	bytes	The parameters passed into the contract call. This field should only be populated when the paired TransactionBody in the record stream is not a ContractCreateTransactionBody or a ContractCallTransactionBody.
`signerNonce`	int64	The value of the signer account nonce. This value can be null.

ContractLoginfo

The log information for an event returned by a smart contract function call. One function call may return several such events.

Field	Type	Description
`contractID`	ContractID	Address of a contract that emitted the event
`bloom`	bytes	Bloom filter for a particular log
`topic`	repeated bytes	Topics of a particular event
`data`	bytes	Event data

ContractStateChange

The storage changes to a smart contract’s storage as a side effect of the function call.

Field	Type	Description
`contractID`	ContractID	The contract to which the storage changes apply to
`storageChanges`	repeated StorageChange	The list of storage changes

StorageChange

A storage slot change description.

Field	Type	Description
`slot`	bytes	The storage slot changed. Up to 32 bytes, big-endian, zero bytes left trimmed
`valueRead`	bytes	The value read from the storage slot. Up to 32 bytes, big-endian, zero bytes left trimmed. Because of the way SSTORE operations are charged the slot is always read before being written to
`valueWritten`	google.protobuf.BytesValue	The new value written to the slot. Up to 32 bytes, big-endian, zero bytes left trimmed. If a value of zero is written the valueWritten will be present but the inner value will be absent. If a value was read and not written this value will not be present.
