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

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

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
