Trait Implementations

impl AsRef<Reference> for Error

fn as_ref(&self) -> &Reference

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

impl Clone for Error

fn clone(&self) -> Error

Returns a copy 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 description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

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

Returns the lower-level source of this error, if any.

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.

Returns a human-readable description of the error.

fn name(&self) -> String

Returns a name specifiying the type of error.

impl InstanceOf for Error

fn instance_of(reference: &Reference) -> bool

Checks whenever a given Reference if of type Self.

impl PartialEq for Error

fn eq(&self, other: &Error) -> 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 ReferenceType for Error

unsafe fn from_reference_unchecked(reference: Reference) -> Self

Converts a given reference into a concrete reference-like wrapper. Doesn’t do any type checking; highly unsafe to use!
