pub struct RegistryState { /* private fields */ }
Expand description

State object associated with the registry handling for smithay’s client toolkit.

This object provides utilities to cache bound globals that are needed by multiple modules.

Implementations§

source§

impl RegistryState

source

pub fn new(global_list: &GlobalList) -> Self

Creates a new registry handle.

This type may be used to bind globals as they are advertised.

source

pub fn registry(&self) -> &WlRegistry

source

pub fn globals(&self) -> impl Iterator<Item = &Global> + '_

Returns an iterator over all globals.

This list may change if the compositor adds or removes globals after initial enumeration.

No guarantees are provided about the ordering of the globals in this iterator.

source

pub fn globals_by_interface<'a>( &'a self, interface: &'a str ) -> impl Iterator<Item = &Global> + 'a

Returns an iterator over all globals implementing the given interface.

This may be more efficient than searching Self::globals.

source

pub fn bind_one<I, D, U>( &self, qh: &QueueHandle<D>, version: RangeInclusive<u32>, udata: U ) -> Result<I, BindError>
where D: Dispatch<I, U> + 'static, I: Proxy + 'static, U: Send + Sync + 'static,

Binds a global, returning a new object associated with the global.

This should not be used to bind globals that have multiple instances such as wl_output; use Self::bind_all instead.

source

pub fn bind_specific<I, D, U>( &self, qh: &QueueHandle<D>, name: u32, version: RangeInclusive<u32>, udata: U ) -> Result<I, BindError>
where D: Dispatch<I, U> + 'static, I: Proxy + 'static, U: Send + Sync + 'static,

Binds a global, returning a new object associated with the global.

This binds a specific object by its name as provided by the RegistryHandler::new_global callback.

source

pub fn bind_all<I, D, U, F>( &self, qh: &QueueHandle<D>, version: RangeInclusive<u32>, make_udata: F ) -> Result<Vec<I>, BindError>
where D: Dispatch<I, U> + 'static, I: Proxy + 'static, F: FnMut(u32) -> U, U: Send + Sync + 'static,

Binds all globals with a given interface.
