Enum ExecutionResult

pub enum ExecutionResult<HaltReasonTy = HaltReason> {
    Success {
        reason: SuccessReason,
        gas_used: u64,
        gas_refunded: u64,
        logs: Vec<Log>,
        output: Output,
    },

    },
    Halt {
        reason: HaltReasonTy,

    },
}

Result of a transaction execution

Variants

Success

Returned successfully

Fields

reason: SuccessReason

gas_used: u64

gas_refunded: u64

logs: Vec<Log>

output: Output

Revert

Reverted by REVERT opcode that doesn’t spend all gas

Fields

gas_used: u64

output: Bytes

Halt

Reverted for various reasons and spend all gas

Fields

reason: HaltReasonTy

gas_used: u64

Halting will spend all the gas, and will be equal to gas_limit.

Implementations

impl<HaltReasonTy> ExecutionResult<HaltReasonTy>

pub fn is_success(&self) -> bool

Returns if transaction execution is successful.

1 indicates success, 0 indicates revert.

https://eips.ethereum.org/EIPS/eip-658

pub fn map_haltreason<F, OHR>(self, op: F) -> ExecutionResult<OHR>

where F: FnOnce(HaltReasonTy) -> OHR,

Maps a DBError to a new error type using the provided closure, leaving other variants unchanged.

pub fn created_address(&self) -> Option<Address>

Returns created address if execution is Create transaction and Contract was created.

pub fn is_halt(&self) -> bool

Returns true if execution result is a Halt.

pub fn output(&self) -> Option<&Bytes>

Returns the output data of the execution.

Returns None if the execution was halted.

pub fn into_output(self) -> Option<Bytes>

Consumes the type and returns the output data of the execution.

Returns None if the execution was halted.

pub fn logs(&self) -> &[Log]

Returns the logs if execution is successful, or an empty list otherwise.

pub fn into_logs(self) -> Vec<Log>

Consumes self and returns the logs if execution is successful, or an empty list otherwise.

pub fn gas_used(&self) -> u64

Returns the gas used.

Trait Implementations

impl<HaltReasonTy> Clone for ExecutionResult<HaltReasonTy>

where HaltReasonTy: Clone,

fn clone(&self) -> ExecutionResult<HaltReasonTy>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<HaltReasonTy> Debug for ExecutionResult<HaltReasonTy>

where HaltReasonTy: Debug,

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<'de, HaltReasonTy> Deserialize<'de> for ExecutionResult<HaltReasonTy>

where HaltReasonTy: Deserialize<'de>,

fn deserialize<__D>( __deserializer: __D, ) -> Result<ExecutionResult<HaltReasonTy>, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<HaltReasonTy> Hash for ExecutionResult<HaltReasonTy>

where HaltReasonTy: Hash,

Layout

Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
