Struct WebViewCollection 

pub struct WebViewCollection {
    webviews: HashMap<WebViewId, WebView>,
    pub(crate) creation_order: Vec<WebViewId>,
    active_webview_id: Option<WebViewId>,
}

Fields

webviews: HashMap<WebViewId, WebView>

List of top-level browsing contexts. Modified by EmbedderMsg::WebViewOpened and EmbedderMsg::WebViewClosed, and we exit if it ever becomes empty.

creation_order: Vec<WebViewId>

The order in which the webviews were created.

active_webview_id: Option<WebViewId>

The WebView that is currently active. This is the WebView that is shown and has input focus.

Implementations

impl WebViewCollection

pub fn add(&mut self, webview: WebView)

pub fn remove(&mut self, id: WebViewId) -> Option<WebView>

Removes a webview from the collection by WebViewId. If the removed WebView was the active WebView then the next newest WebView will be activated.

pub fn get(&self, id: WebViewId) -> Option<&WebView>

pub fn contains(&self, id: WebViewId) -> bool

pub fn active(&self) -> Option<&WebView>

pub fn active_id(&self) -> Option<WebViewId>

pub fn newest(&self) -> Option<&WebView>

Gets a reference to the most recently created webview, if any.

pub fn all_in_creation_order( &self, ) -> impl Iterator<Item = (WebViewId, &WebView)>

pub fn values(&self) -> impl Iterator<Item = &WebView>

Returns an iterator over all webview references (in arbitrary order).

pub fn is_empty(&self) -> bool

Returns true if the collection contains no webviews.

pub(crate) fn activate_webview(&mut self, id_to_activate: WebViewId)

pub(crate) fn activate_webview_by_index(&mut self, index: usize)

Trait Implementations

impl Default for WebViewCollection

fn default() -> WebViewCollection
