Struct ParentHandle 

pub struct ParentHandle { /* private fields */ }

Opaque pair of platform handles describing a parent window for a native OS dialog. Construct with ParentHandle::from_window on the main thread.

Implements HasWindowHandle and HasDisplayHandle so backend code can hand it directly to APIs like rfd::AsyncFileDialog::set_parent without an intermediate adapter type.

Implementations

impl ParentHandle

pub fn from_window<W>(window: &W) -> Option<Self>

where W: HasWindowHandle + HasDisplayHandle + ?Sized,

Extract the platform handles from a winit window.

MUST be called on the main thread — winit’s handle accessors are documented as main-thread-only on macOS / Wayland. Returns None if either handle accessor fails (rare; mostly during teardown when the underlying surface is already gone).

pub fn raw_window_handle(&self) -> RawWindowHandle

Raw window handle bytes. Use when the consuming API wants the enum directly rather than the borrowed WindowHandle<'_> returned by HasWindowHandle::window_handle.

pub fn raw_display_handle(&self) -> RawDisplayHandle

Raw display handle bytes. Paired with Self::raw_window_handle.
