Struct kas::app::raw_window_handle::DisplayHandle
pub struct DisplayHandle<'a> { /* private fields */ }
Expand description
The handle to the display controller of the windowing system.
This is the primary return type of the HasDisplayHandle
trait. It is guaranteed to contain
a valid platform-specific display handle for its lifetime.
Get the underlying raw display handle with the HasRawDisplayHandle
trait.
Implementations§
§impl<'a> DisplayHandle<'a>
impl<'a> DisplayHandle<'a>
pub unsafe fn borrow_raw(raw: RawDisplayHandle) -> DisplayHandle<'a>
pub unsafe fn borrow_raw(raw: RawDisplayHandle) -> DisplayHandle<'a>
Create a DisplayHandle
from a RawDisplayHandle
.
Safety
The RawDisplayHandle
must be valid for the lifetime.
