Struct runestick::VmError

pub struct VmError { /* fields omitted */ }

Errors raised by the execution of the virtual machine.

Implementations

impl VmError

pub fn panic<D>(message: D) -> Self where
    D: BoxedPanic, 

Return an error encapsulating a panic.

pub fn bad_argument<T>(arg: usize, value: &Value) -> Result<Self, VmError> where
    T: ReflectValueType, 

Bad argument.

pub fn expected<T>(actual: ValueTypeInfo) -> Self where
    T: ReflectValueType, 

Construct an expected error.

pub fn expected_any(actual: ValueTypeInfo) -> Self

Construct an expected any error.

pub fn kind(&self) -> &VmErrorKind

Access the underlying error kind.

pub fn into_unwinded(self, unit: &Arc<Unit>, ip: usize) -> Self

Convert into an unwinded vm error.

pub fn into_unwound(self) -> (Self, Option<(Arc<Unit>, usize)>)

Unpack an unwinded error, if it is present.

pub fn unpack_critical(self) -> Result<Self, Self>

Unsmuggles the vm error, returning Ok(Self) in case the error is critical and should be propagated unaltered.

Trait Implementations

impl Debug for VmError

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

Formats the value using the given formatter.

impl Display for VmError

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

Formats the value using the given formatter.

impl Error for VmError

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

The lower-level source of this error, if any.

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()

if let Err(e) = "xc".parse::<u32>() { // Print e itself, no need for description(). eprintln!("Error: {}", e); }

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

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl<E> From<E> for VmError where
    VmErrorKind: From<E>, 

fn from(err: E) -> Self

Performs the conversion.
