Implementations

impl VmError

pub fn with_src(self, src: SpanWithSource<Arc<str>>) -> VmError

Return the error with the given source context added.

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.

impl From<BacktraceError> for VmError

fn from(v: BacktraceError) -> VmError

Converts to this type from the input type.

impl From<CompileError> for VmError

fn from(v: CompileError) -> VmError

Converts to this type from the input type.

impl From<CustomValError> for VmError

fn from(v: CustomValError) -> VmError

Converts to this type from the input type.

impl From<String> for VmError

fn from(v: String) -> VmError

Converts to this type from the input type.

impl PartialEq for VmError

fn eq(&self, other: &VmError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
