Module error 

Error Types

This module defines the error types used throughout the MQTT client library, providing detailed information about potential failures, from transport issues to protocol violations.

Structs

ErrorPlaceHolder

A placeholder error type used in generic contexts where the specific transport error is not yet known. This is a common pattern for implementing encode methods that need to return a Result compatible with the client’s error type.

Enums

ConnectReasonCode

Represents the reason codes for a connection refusal (CONNACK).

MqttError

The primary error enum for the MQTT client.

ProtocolError

Enumerates specific MQTT protocol errors.
