Enum aptos_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
