Implementations

impl WebView

pub fn new(system_color_scheme: ColorScheme, js_policy: JsPolicy) -> Self

pub fn set_css_strategy(&mut self, strategy: CssApplicationStrategy)

Set the CSS application strategy.

Default is Incremental.

pub fn set_js_policy(&mut self, policy: JsPolicy)

Sets the JavaScript execution policy.

The policy is applied to <noscript> parsing on the next document load and takes effect immediately for execution: disabling it drops the JS runtime, cancels pending script work, and stops running scripts.

pub fn js_policy(&self) -> JsPolicy

Returns the current JavaScript execution policy.

pub fn tick(&mut self) -> Vec<WebViewTask>

pub fn on_html_fetched(&mut self, html: String, document_url: Url)

pub fn on_css_fetched(&mut self, css: String)

pub fn on_css_fetched_from(&mut self, css: String, stylesheet_url: &Url)

pub fn on_image_fetched(&mut self, source: String, bytes: &[u8]) -> Result<()>

Decodes a fetched image and rebuilds layout using its intrinsic size.

pub fn on_audio_fetched(&mut self, source: String, bytes: &[u8])

Stores fetched audio bytes for the matching <audio> control.

pub fn on_script_fetched(&mut self, index: usize, source: String)

Executes or queues a fetched external classic script by scheduling mode.

pub fn on_script_fetch_failed(&mut self, index: usize)

Records a failed external classic script without aborting page loading.

pub fn on_dynamic_script_fetched(&mut self, node_id: u64, source: String)

Executes a fetched dynamically inserted script and dispatches load.

pub fn on_dynamic_script_fetch_failed(&mut self, node_id: u64)

Dispatches error for a dynamically inserted script that failed to load.

pub fn on_dynamic_style_fetched(&mut self, node_id: u64, source: String)

pub fn on_dynamic_style_fetch_failed(&mut self, node_id: u64)

pub fn on_js_fetch_succeeded( &mut self, request_id: u64, response: JsFetchResponse, )

Resolves a JavaScript fetch() request with a network response.

pub fn on_js_fetch_failed(&mut self, request_id: u64, reason: String)

Rejects a JavaScript fetch() request after a network failure.

pub fn on_iframe_fetched(&mut self, dom_id: u64, html: String)

Installs parsed iframe HTML as the host element’s contentDocument and fires its load event.

pub fn on_iframe_fetch_failed(&mut self, dom_id: u64)

Marks an iframe load as failed so later contentDocument accesses do not keep re-queuing a fetch.

pub fn on_devtools_response(&mut self, id: u64, result: String)

Settles a DevTools inspection request with its JSON envelope.

pub fn update_page(&mut self)

Update page (e.g. DOM changed)

This is a stub method for now.

pub fn on_js_click(&mut self, dom_id: u32) -> bool

Dispatches a click on the given DOM snapshot node id to the page’s JS.

Resolves the live DOM node behind the snapshot id, translates it to the JS-facing dom id and hands the click to the JS thread. Returns whether a redraw is needed; the JS result triggers the relayout once applied.

pub fn on_js_scroll(&mut self, dom_id: u32) -> bool

Dispatches a scroll event on the given DOM snapshot node id to the page’s JS.

Resolves the live DOM node behind the snapshot id, translates it to the JS-facing dom id and hands the scroll to the JS thread. Returns whether a redraw is needed; the JS result triggers the relayout once applied.

pub fn navigate(&mut self)

pub fn set_system_color_scheme(&mut self, scheme: ColorScheme)

pub fn title(&self) -> Option<&String>

pub fn relayout(&mut self, viewport: (f32, f32))

pub fn layout_and_info(&self) -> Option<(&LayoutNode, &InfoNode)>

現在描画可能な Layout / Info を返す（なければ None）

pub fn layout_and_info_mut(&mut self) -> Option<(&LayoutNode, &mut InfoNode)>

pub fn document_info(&self) -> Option<&DocumentInfo>

Returns document info

pub fn document_url(&self) -> Option<&Url>

pub fn base_url(&self) -> Option<&Url>

pub fn needs_redraw(&self) -> bool

pub fn clear_redraw_flag(&mut self)

Trait Implementations

impl Default for WebView

fn default() -> Self

Returns the “default value” for a type.
