Errors that can occur during decoding.

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.

InsufficientData

Not enough bytes in the buffer.

MalformedVbi

Variable Byte Integer uses more than 4 bytes.

InvalidUtf8

String bytes are not valid UTF-8.

StringContainsNull

A UTF-8 string contains the null character U+0000.

InvalidValue

A reserved or unknown field value was encountered.

InvalidPropertyId

An unknown property identifier was encountered.

DuplicateProperty

A property that may appear at most once was included more than once (Protocol Error, §2.2.2.2).

InvalidFlags

Fixed header flags are wrong for the packet type.

InvalidProtocol

The protocol name or version in CONNECT is wrong.

LengthMismatch

Remaining length does not match actual content.

TrailingBytes

A packet’s defined fields were decoded but unread bytes remain in its body.

InvalidPacketId

A packet identifier was zero, which is invalid.

InvalidSubscriptionOptions

A subscription options byte set reserved bits.

TooLong

A dynamically sized value exceeds the maximum allowed length.

Trait Implementations

impl Clone for DecodeError

fn clone(&self) -> DecodeError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DecodeError

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

Formats the value using the given formatter.

impl Display for DecodeError

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

Formats the value using the given formatter.

impl Error for DecodeError

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<DecodeError> for Error

fn from(e: DecodeError) -> Self

Converts to this type from the input type.

impl PartialEq for DecodeError

fn eq(&self, other: &DecodeError) -> 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 Copy for DecodeError
