Execution was finished successfully

Implementations

source

impl ExecutionResult

source

pub fn precondition_failure(error: Error) -> ExecutionResult

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.

source

pub fn is_success(&self) -> bool

Returns true if this is a successful variant.

source

pub fn is_failure(&self) -> bool

Returns true if this is a failure variant.

source

pub fn has_precondition_failure(&self) -> bool

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.

source

pub fn cost(&self) -> Gas

Returns gas cost of execution regardless of variant.

source

pub fn transfers(&self) -> &Vec<TransferAddr>ⓘNotable traits for Vec<u8, A>`impl<A> Write for Vec<u8, A> where A: Allocator,`

Returns list of transfers regardless of variant.

source

pub fn execution_journal(&self) -> &ExecutionJournal

The journal of transforms regardless of variant.

source

pub fn with_cost(self, cost: Gas) -> Self

Returns a new execution result with updated gas cost.

This method preserves the ExecutionResult variant and updates the cost field only.

source

pub fn with_transfers(self, transfers: Vec<TransferAddr>) -> Self

Returns a new execution result with updated transfers field.

This method preserves the ExecutionResult variant and updates the transfers field only.

source

pub fn with_journal(self, execution_journal: ExecutionJournal) -> Self

Returns a new execution result with an updated execution journal.

This method preserves the ExecutionResult variant and updates the execution_journal field only.

source

pub fn as_error(&self) -> Option<&Error>

Returns error value, if possible.

Returns a reference to a wrapped error::Error instance if the object is a failure variant.

source

pub fn take_error(self) -> Option<Error>

Consumes ExecutionResult instance and optionally returns error::Error instance for ExecutionResult::Failure variant.

source

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 condition.

source

pub fn new_payment_code_error(
 error: Error,
 max_payment_cost: Motes,
 account_main_purse_balance: Motes,
 gas_cost: Gas,
 account_main_purse_balance_key: Key,
 proposer_main_purse_balance_key: Key
) -> Result<ExecutionResult, Error>

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.
