Struct iced::window::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.
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
Users can safely assume that non-null
/0
fields are valid handles, and it is up to the
implementer of this trait to ensure that condition is upheld.
Despite that qualification, implementors should still make a best-effort attempt to fill in all available fields. If an implementation doesn’t, and a downstream user needs the field, it should try to derive the field from other fields the implementer does provide via whatever methods the platform provides.
It is not possible to invalidate a DisplayHandle
on any platform without additional unsafe code.
pub fn as_raw(&self) -> RawDisplayHandle
pub fn as_raw(&self) -> RawDisplayHandle
Get the underlying raw display handle.
