}Expand description
Represents the result of an execution specified by
crate::core::engine_state::ExecuteRequest.
Variants
An error condition that happened during execution
Fields of Failure
error: ErrorError causing this Failure variant.
execution_effect: ExecutionEffectContains all the effects that occurred during execution up to the point of the failure.
transfers: Vec<TransferAddr>List of transfers that happened during execution up to the point of the failure.
cost: GasGas consumed up to the point of the failure.
Execution was finished successfully
Fields of Success
execution_effect: ExecutionEffectExecution effect.
transfers: Vec<TransferAddr>List of transfers.
cost: GasGas cost.
Implementations
Constructs ExecutionResult::Failure that has 0 cost and no effects.
This is the case for failures that we can’t (or don’t want to) charge
for, like PreprocessingError or InvalidNonce.
Returns true if this is a successful variant.
Returns true if this is a failure variant.
Returns true if this is a precondition failure.
Precondition variant is further described as an execution failure which does not have any effects, and has a gas cost of 0.
Returns execution effects regardless of variant.
Returns list of transfers regardless of variant.
Returns a new execution result with updated gas cost.
This method supports preserves the ExecutionResult variant and updates the cost field
only.
Returns a new execution result with updated execution effects.
This method preserves the ExecutionResult variant and updates the
execution_effect field only.
Returns a new execution result with updated transfers field.
This method supports preserves the ExecutionResult variant and updates the
transfers field only.
Returns error value, if possible.
Returns a reference to a wrapped error::Error instance if the object is a failure
variant.
Consumes ExecutionResult instance and optionally returns error::Error instance for
ExecutionResult::Failure variant.
pub fn check_forced_transfer(
&self,
payment_purse_balance: Motes,
gas_price: u64
) -> Option<ForcedTransferResult>
pub fn check_forced_transfer(
&self,
payment_purse_balance: Motes,
gas_price: u64
) -> Option<ForcedTransferResult>
Checks the transfer status of a payment code.
This method converts the gas cost of the execution result into motes using supplied
gas_price, and then a check is made to ensure that user deposited enough funds in the
payment purse (in motes) to cover the execution of a payment code.
Returns None if user deposited enough funds in payment purse and the execution result was
a success variant, otherwise a wrapped ForcedTransferResult that indicates an error
codition.
Creates a new payment code error.
The method below creates an ExecutionResult with precomputed effects of a
“finalize_payment”.
The effects that are produced as part of this process would subract max_payment_cost from
account’s main purse, and add max_payment_cost to proposer account’s balance.
