Struct JsErasedError 

pub struct JsErasedError { /* private fields */ }

Erased version of JsError.

This is mainly useful to convert a JsError into an Error that also implements Send + Sync, which makes it compatible with error reporting tools such as anyhow, eyre or miette.

Generally, the conversion from JsError to JsErasedError is unidirectional, since any JsError that is a JsValue is converted to its string representation instead. This will lose information if that value was an object, a symbol or a big int.

Implementations

impl JsErasedError

pub fn as_opaque(&self) -> Option<&str>

Gets the inner str if the error is an opaque error, or None otherwise.

pub const fn as_native(&self) -> Option<&JsErasedNativeError>

Gets the inner JsErasedNativeError if the error is a native error, or None otherwise.

pub const fn as_engine(&self) -> Option<&ErasedEngineError>

Gets the inner ErasedEngineError if the error is an engine error, or None otherwise.

Trait Implementations

impl Clone for JsErasedError

fn clone(&self) -> JsErasedError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for JsErasedError

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

Formats the value using the given formatter.

impl Display for JsErasedError

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

Formats the value using the given formatter.

impl Drop for JsErasedError

fn drop(&mut self)

Executes the destructor for this type.

impl Error for JsErasedError

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 Finalize for JsErasedError

fn finalize(&self)

Cleanup logic for a type.

impl PartialEq for JsErasedError

fn eq(&self, other: &JsErasedError) -> 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.

impl Trace for JsErasedError

unsafe fn trace(&self, tracer: &mut Tracer)

Marks all contained Gcs.

unsafe fn trace_non_roots(&self)

Trace handles located in GC heap, and mark them as non root.

fn run_finalizer(&self)

Runs Finalize::finalize on this object and all contained subobjects.
