Struct UnknownEnumValue

pub struct UnknownEnumValue(pub i32);

An error indicating that an unknown enumeration value was encountered.

The Protobuf spec mandates that enumeration value sets are ‘open’, so this error’s value represents an integer value unrecognized by the presently used enum definition.

0: i32

Trait Implementations

impl Clone for UnknownEnumValue

fn clone(&self) -> UnknownEnumValue

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for UnknownEnumValue

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

Formats the value using the given formatter.

impl Display for UnknownEnumValue

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

Formats the value using the given formatter.

impl Error for UnknownEnumValue

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 PartialEq for UnknownEnumValue

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