The representation of a protocol object

Fields

interface: &'static str

Interface name of this object

version: u32

Version of this object

requests: &'static [MessageDesc]

Description of the requests of this object

events: &'static [MessageDesc]

Description of the events of this object

meta: Meta

Metadata associated to this object (ex: its event queue client side)

childs_from_events: fn(_: u16, _: u32, _: &Meta) -> Option<Object<Meta>>

A function which, from an opcode, a version, and the Meta, creates a child object associated with this event if any

childs_from_requests: fn(_: u16, _: u32, _: &Meta) -> Option<Object<Meta>>

A function which, from an opcode, a version, and the Meta, creates a child object associated with this request if any

Methods

impl<Meta: ObjectMetadata> Object<Meta>

pub fn from_interface<I: Interface>(version: u32, meta: Meta) -> Object<Meta>

Create an Object corresponding to given interface and version

pub fn event_child(&self, opcode: u16) -> Option<Object<Meta>>

Create an optional Object corresponding to the possible new_id associated with given event opcode

pub fn request_child(&self, opcode: u16) -> Option<Object<Meta>>

Create an optional Object corresponding to the possible new_id associated with given request opcode

pub fn is_interface<I: Interface>(&self) -> bool

Check whether this object is of given interface

pub fn placeholder(meta: Meta) -> Object<Meta>

Create a placeholder object that will be filled-in by the message logic

Trait Implementations

impl<Meta: Clone + ObjectMetadata> Clone for Object<Meta>

fn clone(&self) -> Object<Meta>
