Struct raw_window_handle::Win32WindowHandle

#[non_exhaustive]
pub struct Win32WindowHandle {
    pub hwnd: NonZeroIsize,
    pub hinstance: Option<NonZeroIsize>,
}

Raw window handle for Win32.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

hwnd: NonZeroIsize

A Win32 HWND handle.

hinstance: Option<NonZeroIsize>

The GWLP_HINSTANCE associated with this type’s HWND.

Implementations

impl Win32WindowHandle

pub fn new(hwnd: NonZeroIsize) -> Self

Create a new handle to a window.

Example

let window: HWND;
let mut handle = Win32WindowHandle::new(NonZeroIsize::new(window.0).unwrap());
// Optionally set the GWLP_HINSTANCE.
let hinstance = NonZeroIsize::new(unsafe { GetWindowLongPtrW(window, GWLP_HINSTANCE) }).unwrap();
handle.hinstance = hinstance;

Trait Implementations

impl Clone for Win32WindowHandle

fn clone(&self) -> Win32WindowHandle

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Win32WindowHandle

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<Win32WindowHandle> for RawWindowHandle

fn from(value: Win32WindowHandle) -> Self

Converts to this type from the input type.

impl Hash for Win32WindowHandle

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Win32WindowHandle

fn eq(&self, other: &Win32WindowHandle) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
