Struct HaikuWindowHandle

#[non_exhaustive]
pub struct HaikuWindowHandle {
    pub b_window: NonNull<c_void>,
    pub b_direct_window: Option<NonNull<c_void>>,
}

Raw window handle for Haiku.

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.

b_window: NonNull<c_void>

A pointer to a BWindow object

b_direct_window: Option<NonNull<c_void>>

A pointer to a BDirectWindow object that might be null

Implementations

impl HaikuWindowHandle

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

Create a new handle to a window.

Example

let b_window: NonNull<BWindow>;
let mut handle = HaikuWindowHandle::new(b_window.cast());
// Optionally set `b_direct_window`.
handle.b_direct_window = None;

Trait Implementations

impl Clone for HaikuWindowHandle

fn clone(&self) -> HaikuWindowHandle

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for HaikuWindowHandle

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

Formats the value using the given formatter.

impl From<HaikuWindowHandle> for RawWindowHandle

fn from(value: HaikuWindowHandle) -> Self

Converts to this type from the input type.

impl Hash for HaikuWindowHandle

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 HaikuWindowHandle

fn eq(&self, other: &HaikuWindowHandle) -> 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.
