Struct wayland_commons::map::ObjectMap

source · [−]

pub struct ObjectMap<Meta: ObjectMetadata> { /* private fields */ }

Expand description

A holder for the object store of a connection

Keeps track of which object id is associated to which interface object, and which is currently unused.

Implementations

source

impl<Meta: ObjectMetadata> ObjectMap<Meta>

source

pub fn new() -> ObjectMap<Meta>

Create a new empty object map

source

pub fn find(&self, id: u32) -> Option<Object<Meta>>

Find an object in the store

source

pub fn remove(&mut self, id: u32)

Remove an object from the store

Does nothing if the object didn’t previously exists

source

pub fn insert_at(&mut self, id: u32, object: Object<Meta>) -> Result<(), ()>

Insert given object for given id

Can fail if the requested id is not the next free id of this store. (In which case this is a protocol error)

source

pub fn client_insert_new(&mut self, object: Object<Meta>) -> u32

Allocate a new id for an object in the client namespace

source

pub fn server_insert_new(&mut self, object: Object<Meta>) -> u32

Allocate a new id for an object in the server namespace

source

pub fn with<T, F: FnOnce(&mut Object<Meta>) -> T>(
 &mut self,
 id: u32,
 f: F
) -> Result<T, ()>

Mutably access an object of the map

source

pub fn with_all<F: FnMut(u32, &mut Object<Meta>)>(&mut self, f: F)

Mutably access all objects of the map in sequence
