Trait Implementations

impl AsMut<Val> for ReferenceError

fn as_mut(&mut self) -> &mut Any

Converts this type into a mutable reference of the (usually inferred) input type.

impl AsRef<Val> for ReferenceError

fn as_ref(&self) -> &Any

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for ReferenceError

fn clone(&self) -> ReferenceError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ReferenceError

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

Formats the value using the given formatter.

impl Deref for ReferenceError

type Target = Val

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl DerefMut for ReferenceError

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.

impl Display for ReferenceError

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

Formats the value using the given formatter.

impl DynCast for ReferenceError

fn instanceof(val: &Any) -> bool

Implementation of val instanceof ThisType.

fn unchecked_from_val(v: Any) -> Self

Zero-cost unchecked conversion from Val into Self.

fn unchecked_from_val_ref(v: &Any) -> &Self

Zero-cost unchecked conversion from &Val into &Self.

fn has_type<T>(&self) -> bool

where T: DynCast,

fn dyn_into<T>(self) -> Result<T, Self>

where T: DynCast,

fn dyn_ref<T>(&self) -> Option<&T>

where T: DynCast,

fn unchecked_into<T>(self) -> T

where T: DynCast,

fn unchecked_ref<T>(&self) -> &T

where T: DynCast,

fn is_instance_of<T>(&self) -> bool

where T: DynCast,

fn is_type_of(val: &Val) -> bool

Customisable brand check – defaults to instanceof.

impl Error for ReferenceError

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<&ReferenceError> for Any

fn from(x: &ReferenceError) -> Any

Converts to this type from the input type.

impl From<ReferenceError> for Error

fn from(e: ReferenceError) -> Error

Converts to this type from the input type.

impl From<ReferenceError> for Any

fn from(x: ReferenceError) -> Any

Converts to this type from the input type.

impl FromVal for ReferenceError

fn from_val(v: &Any) -> Self

Creates a Val object from another

fn take_ownership(v: Handle) -> Self

Takes the ownership of a handle

fn as_handle(&self) -> Handle

Returns the raw js handle

impl PartialEq for ReferenceError

fn eq(&self, other: &ReferenceError) -> 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 PartialOrd for ReferenceError

fn partial_cmp(&self, other: &ReferenceError) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
