Struct WebviewSnapshot 

#[non_exhaustive]
pub struct WebviewSnapshot {
    pub browser_id: i32,
    pub dialogs: NativeDialogObservation,
    pub document: Option<NativeDocumentToken>,
    pub window_label: Option<String>,
    pub window: Option<NativeWindowToken>,
    pub parent_matches: Option<bool>,
    pub bounds: Option<Rect>,
    pub visible: Option<bool>,
}

Native state sampled on the CEF UI thread immediately before a with_webview callback. This does not assert renderer responsiveness or that the view is unobscured on screen.

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.

browser_id: i32

Native browser identity, distinct for each popup.

dialogs: NativeDialogObservation

Native JavaScript dialog observation. Unknown is distinct from absent.

document: Option<NativeDocumentToken>

All-frame document generation validated against the current native frame identities and load state. None means document admission is unavailable.

window_label: Option<String>

Runtime window label; CEF-owned popups have no Tauri window label.

window: Option<NativeWindowToken>

Opaque lifetime of the runtime window. Labels and native handle values may be reused after teardown; this token distinguishes their replacements. None means the runtime could not observe a native window lifetime.

parent_matches: Option<bool>

Whether the actual native parent matches the observed native window. None means the platform could not establish the relationship. A CEF-owned popup always reports None, permanently rather than transiently: CEF owns its native window, so there is no independently observed parent for the runtime to check it against. Offscreen webviews also report None because there is no native browser child.

bounds: Option<Rect>

Current bounds relative to the native parent, in the indicated DPI units. Offscreen bounds are the requested layout, in logical pixels.

visible: Option<bool>

Native view visibility. None means native inspection was unavailable. Visibility is separate from occlusion, minimization, and page lifecycle. Offscreen webviews report their requested visibility.
