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

Tuple Fields of Error

0: StatusCode

MoveAbort(AbortLocation, u64)

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

Tuple Fields of MoveAbort

0: AbortLocation1: u64

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 of ExecutionFailure

status_code: StatusCodelocation: AbortLocationfunction: u16code_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

fn backtrace(&self) -> Option<&Backtrace>

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

Returns a stack backtrace, if available, of where this error occurred.

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
