Struct bevy_window::RawHandleWrapper
source · pub struct RawHandleWrapper {
pub window_handle: RawWindowHandle,
pub display_handle: RawDisplayHandle,
/* private fields */
}
Expand description
A wrapper over RawWindowHandle
and RawDisplayHandle
that allows us to safely pass it across threads.
Depending on the platform, the underlying pointer-containing handle cannot be used on all threads,
and so we cannot simply make it (or any type that has a safe operation to get a RawWindowHandle
or RawDisplayHandle
)
thread-safe.
Fields§
§window_handle: RawWindowHandle
Raw handle to a window.
display_handle: RawDisplayHandle
Raw handle to the display server.
Implementations§
source§impl RawHandleWrapper
impl RawHandleWrapper
sourcepub fn new<W: HasWindowHandle + HasDisplayHandle + 'static>(
window: &WindowWrapper<W>
) -> Result<RawHandleWrapper, HandleError>
pub fn new<W: HasWindowHandle + HasDisplayHandle + 'static>( window: &WindowWrapper<W> ) -> Result<RawHandleWrapper, HandleError>
Creates a RawHandleWrapper
from a WindowWrapper
.
sourcepub unsafe fn get_handle(&self) -> ThreadLockedRawWindowHandleWrapper
pub unsafe fn get_handle(&self) -> ThreadLockedRawWindowHandleWrapper
Returns a HasWindowHandle
+ HasDisplayHandle
impl, which exposes WindowHandle
and DisplayHandle
.
§Safety
Some platforms have constraints on where/how this handle can be used. For example, some platforms don’t support doing window
operations off of the main thread. The caller must ensure the RawHandleWrapper
is only used in valid contexts.
