Expand description
Result type of a bare_call
or bare_instantiate
call as well as ContractsApi::call
and
ContractsApi::instantiate
.
It contains the execution result together with some auxiliary information.
#Note
It has been extended to include events
at the end of the struct while not bumping the
ContractsApi
version. Therefore when SCALE decoding a ContractResult
its trailing data
should be ignored to avoid any potential compatibility issues.
Fields§
§gas_consumed: Weight
How much weight was consumed during execution.
gas_required: Weight
How much weight is required as gas limit in order to execute this call.
This value should be used to determine the weight limit for on-chain execution.
§Note
This can only different from Self::gas_consumed
when weight pre charging
is used. Currently, only seal_call_runtime
makes use of pre charging.
Additionally, any seal_call
or seal_instantiate
makes use of pre-charging
when a non-zero gas_limit
argument is supplied.
storage_deposit: StorageDeposit<Balance>
How much balance was paid by the origin into the contract’s deposit account in order to pay for storage.
The storage deposit is never actually charged from the origin in case of Self::result
is Err
. This is because on error all storage changes are rolled back including the
payment of the deposit.
debug_message: Vec<u8>
An optional debug message. This message is only filled when explicitly requested by the code that calls into the contract. Otherwise it is empty.
The contained bytes are valid UTF-8. This is not declared as String
because
this type is not allowed within the runtime.
Clients should not make any assumptions about the format of the buffer. They should just display it as-is. It is not only a collection of log lines provided by a contract but a formatted buffer with different sections.
§Note
The debug message is never generated during on-chain execution. It is reserved for RPC calls.
result: R
The execution result of the wasm code.
events: Option<Vec<EventRecord>>
The events that were emitted during execution. It is an option as event collection is optional.
