Variants

Credentials(CredentialRequest)

SetSiteExceptions(Vec<String>)

RequestSiteStatus

Fields

request_id: u32

origin: String

SiteAction

Fields

request_id: u32

origin: String

generation: u64

action: String

Navigate(String)

Load the given (already normalised) URL.

ScopedNavigation

Transport representation only: use WebViewEngine::navigate_owned to observe admission before relying on an owned outcome.

Fields

request_id: u32

command: NavigationCommand

CancelScopedNavigation

Fields

request_id: u32

RequestNavigationHistory

Fields

request_id: u32

direction: NavigationDirection

NavigateToHistoryEntry

Fields

request_id: u32

id: u32

GoBack

GoForward

Reload

StopLoading

ExitFullscreen

Ask the native browser host to leave document/video fullscreen.

SetAudioMuted(bool)

Mute or restore native page audio without installing an audio capture handler.

Find

Fields

id: u32

text: String

forward: bool

next: bool

StopFinding

ContextMenuAction

Fields

id: u32

command: u32

SetZoomLevel(f64)

Resize

Viewport size in physical pixels plus the display scale factor.

Fields

width: u32

height: u32

scale_factor: f32

MouseMove

Fields

x: f32

y: f32

MouseButton

Fields

button: MouseButton

down: bool

x: f32

y: f32

Scroll

Scroll by (dx, dy) physical pixels at pointer position (x, y).

Fields

dx: f32

dy: f32

x: f32

y: f32

Key

Fields

key: KeyInput

down: bool

modifiers: KeyModifiers

SetFocused(bool)

Keyboard focus entered / left the page surface.

SetContentFilter(Option<Arc<String>>)

Compiled WebKit content-blocker JSON (None clears the filter). Backends without native content filtering ignore this.

SetNativeFilterRules

Source filter rules for engines with native matching. An empty source preserves current rules. None preserves the enabled state, so an asynchronous list refresh cannot undo a user’s disable action.

Fields

rules: Arc<String>

enabled: Option<bool>

SetContentFilters

Several compiled content-blocker JSON blobs, split because the full filter-list rule set exceeds WebKit’s per-filter cap. An empty chunks clears all filters.

version hashes the source filter lists (not the compiled JSON, since compiler rule ordering isn’t stable across runs); the engine caches each compiled filter under version+index so an unchanged rule set loads from disk instead of recompiling (~280k rules costs several seconds).

Fields

version: u64

chunks: Arc<Vec<Arc<String>>>

SetUserScripts(Arc<Vec<String>>)

Scriptlet-style blocking the declarative content filter can’t express (e.g. skipping YouTube video ads). Run at document-start in all frames.

SetBlockingScripts(Arc<Vec<String>>)

Native blocker supplements, guarded by the top-level site policy.

RequestMediaElement

Find the most useful visible HTML video in the current page. The result is delivered asynchronously as WebViewEvent::MediaElement or WebViewEvent::MediaElementUnavailable. Browser chrome uses the returned viewport geometry to create a live, element-sized PiP rather than mirroring the whole page.

Fields

request_id: u64

RequestMediaElementById

Re-resolve a previously selected media element by its stable page-local identity. Active PiP uses this without silently switching videos.

Fields

request_id: u64

element_id: String

Page

Read or operate the current page’s content. Exactly one WebViewEvent::PageResult with the same id answers it; engines without page automation answer PageFailure::unavailable.

Fields

request_id: u32

request: PageRequest

PaintCapture

Capture the page’s layout for the paint stream: every box and text line the engine laid out (see tilo_paint_stream::snapshot). Exactly one WebViewEvent::PaintSnapshot with the same id answers it.

Fields

request_id: u32

PaintResource

The bytes of a resource the page already loaded, read from the engine’s cache. One WebViewEvent::PaintResource answers it.

Fields

request_id: u32

url: String

ClearWebsiteData

Clear all persistent website data (cookies, caches, storage, service workers). Backends without a data store ignore this.

SetClearOnExit(bool)

ShowDeveloperTools

PermissionDecision

Fields

id: u32

allow: bool

DownloadDecision

Fields

id: u32

allow: bool

CancelNativeDownload

Fields

id: u32

RetryDownload

Retry a user-selected network GET without navigating the visible page.

Fields

id: u32

CancelAllDownloads

Stop admitting downloads and cancel every pending or active transfer.

StartDownload

Start a user-requested download of an absolute HTTP(S) URL.

Fields

uri: String

SetDownloadDestination

Finish WebKit’s asynchronous destination decision with the exact absolute path granted by the desktop file portal.

Fields

id: String

path: String

CancelDownload

Cancel an awaiting or active download by its engine-issued stable id.

Fields

id: String

Trait Implementations

impl Clone for WebViewCommand

fn clone(&self) -> WebViewCommand

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WebViewCommand

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

Formats the value using the given formatter.

impl PartialEq for WebViewCommand

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