Struct Any 

pub struct Any;

Generic MQTT role type

Represents a flexible MQTT role that can behave as either a client or server. This role type is useful for:

• Testing scenarios where both client and server behavior is needed
• Bridge implementations that act as both client and server
• Development tools that need to simulate both roles
• Generic code that works with any MQTT role

This is a zero-sized type used purely for compile-time role identification. When using the Any role, the implementation typically allows all MQTT packet types without role-based restrictions.

Protocol Behavior

The Any role typically allows all MQTT packet types and behaviors, making it the most permissive role type. This flexibility comes at the cost of losing compile-time role-specific validations.

Examples

use mqtt_protocol_core::mqtt;

// Any role can be used for flexible implementations
type FlexibleConnection = mqtt::connection::GenericConnection<mqtt::connection::Any, u16>;

// Role constants can be checked at compile time
assert_eq!(mqtt::connection::Any::IS_CLIENT, false);
assert_eq!(mqtt::connection::Any::IS_SERVER, false);
assert_eq!(mqtt::connection::Any::IS_ANY, true);

Trait Implementations

impl<PacketIdType> RecvBehavior<Any, PacketIdType> for GenericConnection<Any, PacketIdType>

impl RoleType for Any

Implementation of RoleType for Any

Configures the Any role type with the appropriate role flags. Only the IS_ANY flag is set to true, indicating this type can represent any MQTT role (client, server, or both).

const IS_ANY: bool = true

Indicates if this role type can represent any MQTT role

const IS_CLIENT: bool = false

Indicates if this role type represents an MQTT client

const IS_SERVER: bool = false

Indicates if this role type represents an MQTT server/broker
