Struct rune::runtime::VmError

pub struct VmError { /* private fields */ }

Errors raised by the execution of the virtual machine.

Implementations

impl VmError

pub fn emit<O>(&self, out: &mut O, sources: &Sources) -> Result<(), EmitError>where O: WriteColor,

Available on crate feature emit only.

Generate formatted diagnostics capable of referencing source lines and hints.

See prepare for how to use.

impl VmError

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

Return an error encapsulating a panic.

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

Bad argument.

pub fn expected<T>(actual: TypeInfo) -> Selfwhere T: TypeOf,

Construct an expected error.

pub fn expected_any(actual: TypeInfo) -> Self

Construct an expected any error.

pub fn kind(&self) -> &VmErrorKind

Access the underlying error kind.

pub fn into_kind(self) -> VmErrorKind

Access the underlying error kind while consuming the error.

pub fn as_unwound( &self ) -> (&VmErrorKind, Option<(&Arc<Unit>, usize, &[CallFrame])>)

Unpack an unwinded error, if it is present.

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

Unpack an unwinded error, if it is present.

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 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<E> From<E> for VmErrorwhere VmErrorKind: From<E>,

fn from(err: E) -> Self

Converts to this type from the input type.
