Struct smithay_client_toolkit::registry::RegistryState
source · 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
impl RegistryState
sourcepub fn new(global_list: &GlobalList) -> Self
pub fn new(global_list: &GlobalList) -> Self
Creates a new registry handle.
This type may be used to bind globals as they are advertised.
pub fn registry(&self) -> &WlRegistry
sourcepub fn globals(&self) -> impl Iterator<Item = &Global> + '_
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.
sourcepub fn globals_by_interface<'a>(
&'a self,
interface: &'a str,
) -> impl Iterator<Item = &Global> + 'a
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.
sourcepub fn bind_one<I, D, U>(
&self,
qh: &QueueHandle<D>,
version: RangeInclusive<u32>,
udata: U,
) -> Result<I, BindError>
pub fn bind_one<I, D, U>( &self, qh: &QueueHandle<D>, version: RangeInclusive<u32>, udata: U, ) -> Result<I, BindError>
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.
sourcepub fn bind_specific<I, D, U>(
&self,
qh: &QueueHandle<D>,
name: u32,
version: RangeInclusive<u32>,
udata: U,
) -> Result<I, BindError>
pub fn bind_specific<I, D, U>( &self, qh: &QueueHandle<D>, name: u32, version: RangeInclusive<u32>, udata: U, ) -> Result<I, BindError>
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.
