A group of messages

This represents a group of message that can be serialized on the protocol wire. Typically the set of events or requests of a single interface.

Implementations of this trait are supposed to be generated using the wayland-scanner crate.

Associated Types

type Map

The wrapper type for ObjectMap allowing the mapping of Object and NewId arguments to the object map during parsing.

Required methods

fn opcode(&self) -> u16

The opcode of this message

fn is_destructor(&self) -> bool

Whether this message is a destructor

If it is, once send or receive the associated object cannot be used any more.

fn since(&self) -> u32

The minimal object version for which this message exists

fn child<Meta>(opcode: u16, version: u32, meta: &Meta) -> Option<Object<Meta>> where
    Meta: ObjectMetadata, 

Retrieve the child Object associated with this message if any

fn from_raw(msg: Message, map: &mut Self::Map) -> Result<Self, ()>

Construct a message from its raw representation

fn into_raw(self, send_id: u32) -> Message

Turn this message into its raw representation
