Type Alias pallet_contracts::ContractExecResult

pub type ContractExecResult<Balance, EventRecord> = ContractResult<Result<ExecReturnValue, DispatchError>, Balance, EventRecord>;

Result type of a bare_call call as well as ContractsApi::call.

Aliased Type

struct ContractExecResult<Balance, EventRecord> {
    pub gas_consumed: Weight,
    pub gas_required: Weight,
    pub storage_deposit: StorageDeposit<Balance>,
    pub debug_message: Vec<u8>,
    pub result: Result<ExecReturnValue, DispatchError>,
    pub events: Option<Vec<EventRecord>>,
}

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: Result<ExecReturnValue, DispatchError>

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.
