#[repr(transparent)]
pub struct DisplayHandle<'a> { raw: RawDisplayHandle, _marker: PhantomData<&'a *const ()>, }
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§

source§

impl<'a> DisplayHandle<'a>

source

pub unsafe fn borrow_raw(raw: RawDisplayHandle) -> Self

Create a DisplayHandle from a RawDisplayHandle.

Safety

The RawDisplayHandle must be valid for the lifetime.
