Struct OhosNdkWindowHandle

#[non_exhaustive]
pub struct OhosNdkWindowHandle {
    pub native_window: NonNull<c_void>,
}

Raw window handle for Ohos NDK.

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.

native_window: NonNull<c_void>

Implementations

impl OhosNdkWindowHandle

pub fn new(native_window: NonNull<c_void>) -> Self

Create a new handle to an OHNativeWindow on OpenHarmony.

The handle will typically be created from an XComponent, consult the native XComponent Guidelines for more details.

Example

/// Called When the `XComponent` is created.
///
/// See the [XComponent Guidelines](https://gitee.com/openharmony/docs/blob/OpenHarmony-4.0-Release/en/application-dev/napi/xcomponent-guidelines.md)
/// for more details
extern "C" fn on_surface_created_callback(component: *mut OH_NativeXComponent, window: *mut c_void) {
    let handle = OhosNdkWindowHandle::new(NonNull::new(window).unwrap());
}

Trait Implementations

impl Clone for OhosNdkWindowHandle

fn clone(&self) -> OhosNdkWindowHandle

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for OhosNdkWindowHandle

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

Formats the value using the given formatter.

impl From<OhosNdkWindowHandle> for RawWindowHandle

fn from(value: OhosNdkWindowHandle) -> Self

Converts to this type from the input type.

impl Hash for OhosNdkWindowHandle

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 OhosNdkWindowHandle

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

Tests for self and other values to be equal, and is used by ==.

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

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