Module transport 

MQTT Transport Abstraction

This module defines the MqttTransport trait, which abstracts the underlying communication channel (like TCP, UART, etc.), allowing the MQTT client to be hardware and network-stack agnostic.

With the Rust 2024 Edition, this trait uses native async fn, removing the need for the #[async_trait] macro.

Structs

ErrorPlaceHolder

A placeholder error type used in contexts where the actual transport error is not known, such as in the EncodePacket trait.

Traits

MqttTransport

A trait representing a transport for MQTT packets.

TransportError

A marker trait for transport-related errors.
