Enum VMStatus

pub enum VMStatus {
    Executed,
    Error(StatusCode),
    MoveAbort(AbortLocation, u64),
    ExecutionFailure {
        status_code: StatusCode,
        location: AbortLocation,
        function: u16,
        code_offset: u16,
    },
}

A VMStatus is represented as either

• Executed indicating successful execution
• Error indicating an error from the VM itself
• MoveAbort indicating an abort ocurred inside of a Move program

Variants

Executed

The VM status corresponding to an EXECUTED status code

Error(StatusCode)

Indicates an error from the VM, e.g. OUT_OF_GAS, INVALID_AUTH_KEY, RET_TYPE_MISMATCH_ERROR etc. The code will neither EXECUTED nor ABORTED

MoveAbort(AbortLocation, u64)

Indicates an abort from inside Move code. Contains the location of the abort and the code

ExecutionFailure

Indicates an failure from inside Move code, where the VM could not continue exection, e.g. dividing by zero or a missing resource

Fields

status_code: StatusCode

location: AbortLocation

function: u16

code_offset: u16

Implementations

impl VMStatus

pub fn status_code(&self) -> StatusCode

Return the status code for the VMStatus

pub fn move_abort_code(&self) -> Option<u64>

Returns the Move abort code if the status is MoveAbort, and None otherwise

pub fn status_type(&self) -> StatusType

Return the status type for this VMStatus. This is solely determined by the status_code

pub fn keep_or_discard(self) -> Result<KeptVMStatus, StatusCode>

Returns Ok with a recorded status if it should be kept, Err of the error code if it should be discarded

Trait Implementations

impl Clone for VMStatus

fn clone(&self) -> VMStatus

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for VMStatus

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for VMStatus

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for VMStatus

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

Formats the value using the given formatter.

impl Error for VMStatus

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<VMStatus> for TransactionStatus

fn from(vm_status: VMStatus) -> Self

Converts to this type from the input type.

impl Hash for VMStatus

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

where __H: Hasher,

Feeds this value into the given Hasher.

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

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for VMStatus

fn cmp(&self, other: &VMStatus) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for VMStatus

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

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

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for VMStatus

fn partial_cmp(&self, other: &VMStatus) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for VMStatus

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
