FasterHex(Error)

Error propagated from the faster_hex decoding library.

JsValue(JsErrorData)

Error originating from a JavaScript JsValue.

Abi(String)

Error relating to the WASM ABI representation.

NotAnObject

The supplied argument was not a JavaScript object.

NotWasmAbiPointer

The supplied object did not carry a WASM ABI pointer.

NotWasmAbiPointerForClass(String)

The supplied object did not carry a WASM ABI pointer for the named class.

NotAnObjectOfClass(String)

The supplied argument was not an object of the named class type.

NoConstructorOfClass(String)

The object’s constructor could not be obtained for the expected class.

UnableToObtainConstructorName(String)

Implementations

impl Error

pub fn custom<S: ToString>(msg: S) -> Self

Construct a Error::Custom error from any stringifiable message.

pub fn convert<S: Display>(msg: S) -> Self

Construct a Error::Convert error from a displayable conversion message.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for JsValue

fn from(err: Error) -> Self

Converts to this type from the input type.

impl From<JsValue> for Error

fn from(error: JsValue) -> Self

Converts to this type from the input type.
