Module error 

Error types for encoding/decoding operations Error types for MQTT protocol encoding and decoding operations

This module defines the error hierarchy used throughout the codec crate:

• HandshakeError: Errors during the initial MQTT connection handshake
• ProtocolError: Higher-level protocol errors (decode, encode, timeout)
• DecodeError: Specific errors that occur when parsing MQTT packets from bytes
• EncodeError: Specific errors that occur when serializing MQTT packets to bytes
• SendPacketError: Errors that occur when preparing a packet for transmission

Enums

EncodeError

Errors that occur when encoding/serializing MQTT packets to a byte stream

HandshakeError

Errors which can occur during mqtt connection handshake.

ProtocolError
