Validation and serialization failures produced by framing and message codecs.

Variants

InvalidLength(u32)

The header length cannot describe a valid frame.

FrameTooLarge(usize)

The complete frame would exceed MAX_FRAME_SIZE.

Truncated

A fixed or mandatory payload prefix is incomplete.

Fields

message_id: u32

needed: usize

actual: usize

InvalidDeviceId(String)

A station identifier failed its textual or structural validation.

InvalidDefinition(String)

A runtime device definition violates a message-level constraint.

InvalidText

A wire text field is not valid under the selected text policy.

UnsupportedProtocol(u32)

The requested protocol version is outside the supported range.

UnexpectedRoute

A known message was decoded through the wrong protocol role.

Fields

message_id: u32

actual: MessageRoute

expected: &'static str

InvalidValue

A scalar field contains a value forbidden by its wire contract.

Fields

message_id: u32

field: &'static str

value: u64

CountTooLarge

A declared or decoded item count exceeds its bounded capacity.

Fields

message_id: u32

field: &'static str

count: usize

maximum: usize

NonZeroPadding

Reserved bytes in a fixed field are not zero-filled.

Fields

message_id: u32

field: &'static str

TrailingBytes

Bytes remain after decoding a layout that requires exact consumption.

Fields

message_id: u32

count: usize

InvalidAlignment

A payload that requires 32-bit alignment has an invalid length.

Fields

message_id: u32

actual: usize

TextTooLong

A text value exceeds the capacity of its wire field.

Fields

message_id: u32

field: &'static str

actual: usize

maximum: usize

SecretTooLong

Secret key material exceeds its fixed wire capacity.

Fields

field: &'static str

actual: usize

maximum: usize

Wire

The binary reader or writer failed at a known wire offset.

Fields

operation: &'static str

message_id: u32

offset: u64

detail: String

Trait Implementations

impl Clone for CodecError

fn clone(&self) -> CodecError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CodecError

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

Formats the value using the given formatter.

impl Display for CodecError

impl Eq for CodecError

impl Error for CodecError

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
