Struct RawHandleWrapper

pub struct RawHandleWrapper {
    pub window_handle: RawWindowHandle,
    pub display_handle: RawDisplayHandle,
    /* private fields */
}

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

impl RawHandleWrapper

pub fn new<W: HasWindowHandle + HasDisplayHandle + 'static>( window: &WindowWrapper<W>, ) -> Result<RawHandleWrapper, HandleError>

Creates a RawHandleWrapper from a WindowWrapper.

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.
