The underlying nature of the error.

Variants

TypeNotFound(u32)

Cannot find a given type.

WrongShape

Fields

actual: Kind

The actual kind we have to encode

expected: u32

ID of the expected type.

Cannot encode the actual type given into the target type ID.

WrongLength

Fields

actual_len: usize

Length we have

expected_len: usize

Length expected for type.

expected: u32

ID of the expected type.

The types line up, but the expected length of the target type is different from the length of the input value.

NumberOutOfRange

Fields

value: String

A string represenatation of the numeric value that was out of range.

expected: u32

Id of the expected numeric type that we tried to encode it to.

We cannot encode the number given into the target type; it’s out of range.

CannotFindVariant

Fields

name: String

Variant name we can’t find in the expected type.

expected: u32

ID of the expected type.

Cannot find a variant with a matching name on the target type.

Trait Implementations

impl Clone for ErrorKind

fn clone(&self) -> ErrorKind

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ErrorKind

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

Formats the value using the given formatter.

impl Display for ErrorKind

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

Formats the value using the given formatter.

impl Error for ErrorKind

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

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, demand: &mut Demand<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type based access to context intended for error reports.

impl PartialEq<ErrorKind> for ErrorKind

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

This method tests for self and other values to be equal, and is used by ==.

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

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