Struct BorrowedWindow 

pub struct BorrowedWindow<'a>(/* private fields */);

Available on crate feature winio only.

Raw window handle.

Implementations

impl<'a> BorrowedWindow<'a>

pub unsafe fn win32(hwnd: *mut c_void) -> BorrowedWindow<'a>

Available on Windows and crate feature win32 only.

Create from Win32 HWND.

Safety

• The caller must ensure that hwnd is a valid handle for the lifetime 'a.
• hwnd must not be null.
