Struct Provider 

pub struct Provider(/* private fields */);

Available on crate feature net only.

The browser’s document and script network provider.

Implementations

impl Provider

pub fn for_scope( self: &Arc<Provider>, initiator: Initiator, ) -> Arc<ScopedProvider>

Bind a browser-issued principal before handing networking to a document.

pub fn new(waker: Option<Arc<dyn NetWaker>>) -> Provider

pub fn with_user_agent( waker: Option<Arc<dyn NetWaker>>, user_agent: &str, ) -> Provider

pub fn shared(waker: Option<Arc<dyn NetWaker>>) -> Arc<dyn NetProvider>

pub fn shared_with_user_agent( waker: Option<Arc<dyn NetWaker>>, user_agent: &str, ) -> Arc<dyn NetProvider>

pub fn user_agent(&self) -> &str

pub fn is_empty(&self) -> bool

pub fn count(&self) -> usize

pub fn fetch_with_callback( &self, request: Request, callback: Box<dyn FnOnce(Result<(String, Bytes), ProviderError>) + Sync + Send>, )

pub async fn fetch_async( &self, request: Request, ) -> Result<(String, Bytes), ProviderError>

pub async fn fetch_response_async( &self, request: Request, ) -> Result<FetchResponse, ProviderError>

pub async fn fetch_platform_async( &self, request: FetchRequest, ) -> Result<FetchResponse, FetchError>

Trait Implementations

impl FetchProvider for Provider

fn fetch(&self, request: FetchRequest, handler: Box<dyn FetchHandler>)

impl NetProvider for Provider

fn fetch(&self, doc_id: usize, request: Request, handler: Box<dyn NetHandler>)

fn for_child_document(&self, _url: Url) -> Option<Arc<dyn NetProvider>>

Bind a child browsing context. srcdoc inherits the existing principal.

fn resource_initiator(&self) -> Initiator

The native principal held by a document-bound provider.

fn is_noop(&self) -> bool

Whether this provider is a no-op (e.g. DummyNetProvider) that will never deliver resources. When true, callers must NOT register resources as “pending critical” — doing so blocks painting forever, since the completion callback never fires. Used by integrations that feed a pre-rendered DOM and perform no sub-fetches (e.g. aginxbrowser).
