Struct VmError

pub struct VmError { /* private fields */ }

A virtual machine error which includes tracing information.

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) -> Self

where D: 'static + BoxedPanic,

Construct an error containing a panic.

pub fn expected<E>(actual: TypeInfo) -> Self

where E: ?Sized + TypeOf,

Construct an expectation error. The actual type received is actual, but we expected E.

pub fn at(&self) -> &VmErrorAt

Get the location where the error happened.

pub fn chain(&self) -> &[VmErrorAt]

Get the full backtrace of errors and their corresponding instructions.

pub fn overflow() -> Self

Construct an overflow error.

pub fn first_location(&self) -> Option<&VmErrorLocation>

Get the first error location.

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, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for VmError

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

Returns 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, request: &mut Request<'a>)

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

Provides type-based access to context intended for error reports.
