Enum mqttrust_core::encoding::v4::Error

pub enum Error {
    WriteZero,
    InvalidPid(u16),
    InvalidQos(u8),
    InvalidConnectReturnCode(u8),
    InvalidProtocol(String<10>, u8),
    InvalidHeader,
    InvalidLength,
    InvalidString,
}

Errors returned by encode() and decode().

Variants

WriteZero

Not enough space in the write buffer.

It is the caller’s responsiblity to pass a big enough buffer to encode().

InvalidPid(u16)

Tried to encode or decode a ProcessIdentifier==0.

InvalidQos(u8)

Tried to decode a QoS > 2.

InvalidConnectReturnCode(u8)

Tried to decode a ConnectReturnCode > 5.

InvalidProtocol(String<10>, u8)

Tried to decode an unknown protocol.

InvalidHeader

Tried to decode an invalid fixed header (packet type, flags, or remaining_length).

InvalidLength

Trying to encode/decode an invalid length.

The difference with WriteZero/UnexpectedEof is that it refers to an invalid/corrupt length rather than a buffer size issue.

InvalidString

Trying to decode a non-utf8 string.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl From<Error> for EventError

fn from(e: Error) -> Self

Converts to this type from the input type.

impl PartialEq<Error> for Error

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