Enum diem_types::vm_status::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

Fields

status_code: StatusCode

location: AbortLocation

function: u16

code_offset: u16

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

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 Arbitrary for VMStatus

type Parameters = ()

The type of parameters that arbitrary_with accepts for configuration of the generated Strategy. Parameters must implement Default.

type Strategy = TupleUnion<((u32, Arc<fn() -> VMStatus>), (u32, Arc<Map<<StatusCode as Arbitrary>::Strategy, fn(_: StatusCode) -> VMStatus>>), (u32, Arc<Map<(<AbortLocation as Arbitrary>::Strategy, <u64 as Arbitrary>::Strategy), fn(_: (AbortLocation, u64)) -> VMStatus>>), (u32, Arc<Map<(<StatusCode as Arbitrary>::Strategy, <AbortLocation as Arbitrary>::Strategy, <u16 as Arbitrary>::Strategy, <u16 as Arbitrary>::Strategy), fn(_: (StatusCode, AbortLocation, u16, u16)) -> VMStatus>>))>

The type of Strategy used to generate values of type Self.

fn arbitrary_with( _top: <VMStatus as Arbitrary>::Parameters ) -> <VMStatus as Arbitrary>::Strategy

Generates a Strategy for producing arbitrary values of type the implementing type (Self). The strategy is passed the arguments given in args.

fn arbitrary() -> Self::Strategy

Generates a Strategy for producing arbitrary values of type the implementing type (Self).

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)>

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, demand: &mut Demand<'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) -> Selfwhere Self: Sized,

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<VMStatus> for VMStatus

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd<VMStatus> 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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method 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.
