Error during serialization and deserialization

Variants

InvalidConnectReturnCode(u8)

InvalidProtocol

InvalidProtocolLevel(u8)

IncorrectPacketFormat

InvalidPacketType(u8)

InvalidPropertyType(u8)

InvalidQoS(u8)

InvalidSubscribeReasonCode(u8)

PacketIdZero

PayloadSizeIncorrect

PayloadTooLong

PayloadSizeLimitExceeded(usize)

PayloadRequired

TopicNotUtf8

BoundaryCrossed(usize)

包中相关长度值与剩余数据长度不匹配——

MalformedPacket

无法用约定规则解析出包

EmptySubscription

InsufficientBytes(usize)

剩余长度使用了一种可变长度的结构来编码，这种结构使用单一字节表示0-127的值。 无法用约定的规则解析剩余长度——断开

MalformedRemainingLength

包剩余长度大于剩余长度——需要等待其他数据

Trait Implementations

impl Clone for PacketParseError

fn clone(&self) -> PacketParseError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PacketParseError

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

Formats the value using the given formatter.

impl Display for PacketParseError

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

Formats the value using the given formatter.

impl Error for PacketParseError

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 From<FixedHeaderError> for PacketParseError

fn from(value: FixedHeaderError) -> Self

Converts to this type from the input type.

impl PartialEq<PacketParseError> for PacketParseError

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