Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

EmptyPayloadEncoding

A payload encoding was constructed without any identity component.

EmptyCustomEncodingId

A payload encoding literal id is empty.

EmptyCustomEncodingContentType

A payload encoding content type is empty.

InvalidCustomEncodingContentType(String)

A payload encoding content type is not a valid media type.

UnspecifiedPayloadFormat

UPayloadFormat::Unspecified is not a concrete payload encoding.

PayloadWithoutEncoding

Payload bytes require a payload encoding.

EncodingWithoutPayload

A payload encoding requires payload bytes.

EncodingNotRepresentable

A native payload encoding cannot be represented by legacy types.

Fields

encoding: String

Diagnostic identity of the offending encoding.

RegisteredPayloadEncodingAlias

An open identity used a literal reserved for a registered legacy row.

Fields

literal_id: String

Literal identity that aliases a registered legacy row.

registered: String

Canonical registered spelling.

FieldNotRepresentable

A semantic field cannot be represented by legacy types.

Fields

field: &'static str

Name of the offending field.

reason: String

Reason the value is not representable.

InvalidMetadata(String)

The metadata violates the validity rules for its frame message kind.

MessageBuildError(String)

Building a UMessage from projected metadata failed.

Trait Implementations

impl Clone for UFrameMetadataError

fn clone(&self) -> UFrameMetadataError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for UFrameMetadataError

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

Formats the value using the given formatter.

impl Display for UFrameMetadataError

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

Formats the value using the given formatter.

impl Error for UFrameMetadataError

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<UFrameMetadataError> for UFrameAbiError

fn from(value: UFrameMetadataError) -> Self

Converts to this type from the input type.

impl From<UFrameMetadataError> for UFrameFieldsError

fn from(value: UFrameMetadataError) -> Self

Converts to this type from the input type.

impl From<UFrameMetadataError> for UFrameWireError

fn from(value: UFrameMetadataError) -> Self

Converts to this type from the input type.

impl From<UFrameMetadataError> for UWireMetadataError

fn from(value: UFrameMetadataError) -> Self

Converts to this type from the input type.

impl From<UMessageError> for UFrameMetadataError

fn from(value: UMessageError) -> Self

Converts to this type from the input type.

impl PartialEq for UFrameMetadataError

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