}

Result of executing an EVM instruction.

This enum represents all possible outcomes when executing an instruction, including successful execution, reverts, and various error conditions.

Variants

Stop = 1

Encountered a STOP opcode

Return = 2

Return from the current call.

SelfDestruct = 3

Self-destruct the current contract.

Suspend = 4

Temporarily suspended, for CALL/CREATE.

Revert = 16

Revert the transaction.

CallTooDeep = 17

Exceeded maximum call depth.

OutOfFunds = 18

Insufficient funds for transfer.

CreateInitCodeStartingEF00 = 19

Revert if CREATE/CREATE2 starts with 0xEF00.

InvalidEOFInitCode = 20

Invalid EVM Object Format (EOF) init code.

InvalidExtDelegateCallTarget = 21

ExtDelegateCall calling a non EOF contract.

OutOfGas = 32

Out of gas error.

MemoryOOG = 33

Out of gas error encountered during memory expansion.

MemoryLimitOOG = 34

The memory limit of the EVM has been exceeded.

PrecompileOOG = 35

Out of gas error encountered during the execution of a precompiled contract.

InvalidOperandOOG = 36

Out of gas error encountered while calling an invalid operand.

ReentrancySentryOOG = 37

Out of gas error encountered while checking for reentrancy sentry.

OpcodeNotFound = 38

Unknown or invalid opcode.

StateChangeDuringStaticCall = 40

Invalid state modification in static call.

InvalidFEOpcode = 41

An undefined bytecode value encountered during execution.

InvalidJump = 42

Invalid jump destination. Dynamic jumps points to invalid not jumpdest opcode.

NotActivated = 43

The feature or opcode is not activated in this version of the EVM.

StackUnderflow = 44

Attempting to pop a value from an empty stack.

StackOverflow = 45

Attempting to push a value onto a full stack.

OutOfOffset = 46

Invalid memory or storage offset.

CreateCollision = 47

OverflowPayment = 48

Payment amount overflow.

PrecompileError = 49

Error in precompiled contract execution.

NonceOverflow = 50

Nonce overflow.

CreateContractSizeLimit = 51

Exceeded contract size limit during creation.

CreateContractStartingWithEF = 52

Created contract starts with invalid bytes (0xEF).

CreateInitCodeSizeLimit = 53

Exceeded init code size limit (EIP-3860: Limit and meter initcode).

FatalExternalError = 54

Fatal external error. Returned by database.

InvalidImmediateEncoding = 55

Invalid encoding of an instruction’s immediate operand.

Implementations

impl InstructionResult

pub const fn is_ok(self) -> bool

Returns whether the result is a success.

pub const fn is_ok_or_revert(self) -> bool

Returns whether the result is a success or revert (not an error).

pub const fn is_revert(self) -> bool

Returns whether the result is a revert.

pub const fn is_error(self) -> bool

👎Deprecated:

use is_halt instead

Returns whether the result is an error.

pub const fn is_halt(self) -> bool

Returns whether the result is a halt (error).

Trait Implementations

impl Clone for InstructionResult

fn clone(&self) -> InstructionResult

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for InstructionResult

impl Debug for InstructionResult

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

Formats the value using the given formatter.

impl Default for InstructionResult

fn default() -> InstructionResult

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for InstructionResult

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for InstructionResult

impl From<HaltReason> for InstructionResult

fn from(value: HaltReason) -> Self

Converts to this type from the input type.

impl<HaltReasonTr: From<HaltReason>> From<InstructionResult> for SuccessOrHalt<HaltReasonTr>

fn from(result: InstructionResult) -> Self

Converts to this type from the input type.

impl From<LoadError> for InstructionResult

fn from(error: LoadError) -> Self

Converts to this type from the input type.

impl From<SuccessReason> for InstructionResult

fn from(value: SuccessReason) -> Self

Converts to this type from the input type.

impl From<TransferError> for InstructionResult

fn from(e: TransferError) -> Self

Converts to this type from the input type.

impl Hash for InstructionResult

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

impl PartialEq for InstructionResult

fn eq(&self, other: &InstructionResult) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

where __S: Serializer,

Serialize this value into the given Serde serializer.
