Struct runa_orbiter::objects::shm::Shm

pub struct Shm;

Implementation of the wl_shm interface.

Trait Implementations

impl Clone for Shm

fn clone(&self) -> Shm

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Shm

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Shm

fn default() -> Shm

Returns the “default value” for a type.

impl MonoObject for Shm

type SingletonState = ()

A singleton state associated with the object type. This state is associated with the type, so there is only one instance of the state for all objects of the same type. The lifetime of this state is managed by the object store, and it will be dropped when the last object of the type is dropped.

const INTERFACE: &'static str = wl_shm::NAME

The wayland interface implemented by this object.

fn new_singleton_state() -> Self::SingletonState

Create a new instance of the singleton state.

impl<Ctx> Object<Ctx> for Shmwhere Ctx: Client, Ctx::Object: From<ShmPool>,

type Request<'a> where Ctx: 'a = Request

The type of wayland messages that this object can receive. This is what the dispatch method accepts.

type Error = Error

Error returned by the dispatch method.

type Fut<'a> where Ctx: 'a = impl Future<Output = (Result<(), <Shm as Object<Ctx>>::Error>, usize, usize)> + 'a

The future type returned by the dispatch method.

fn dispatch<'a>( ctx: &'a mut Ctx, object_id: u32, msg: Self::Request<'a> ) -> Self::Fut<'a>

Dispatch a wayland request to this object. Returns a future, that resolves to (Result, usize, usize), which are the result of the request, the number of bytes and file descriptors in the request, respectively.

fn on_disconnect( &mut self, _server_ctx: &mut <Ctx as Client>::ServerContext, _state: &mut (dyn Any + 'static) )

A function that will be called when the client disconnects. It should free up allocated resources if any. This function only gets reference to the server context, because:

impl<Ctx> RequestDispatch<Ctx> for Shmwhere Ctx: Client, Ctx::Object: From<ShmPool>,

type Error = Error

type CreatePoolFut<'a> where Ctx: 'a = impl Future<Output = Result<(), <Shm as RequestDispatch<Ctx>>::Error>> + 'a

Type of future returned by create_pool

fn create_pool( ctx: &mut Ctx, object_id: u32, id: NewId, fd: WaylandFd, size: i32 ) -> Self::CreatePoolFut<'_>

create a shm pool
