Struct ParseOutput 

pub struct ParseOutput<I> { /* private fields */ }

Item contracts and parse results returned by Spider::parse. The output returned by a spider’s parse method.

Implementations

impl<I> ParseOutput<I>

pub fn new() -> ParseOutput<I>

Creates a new, empty ParseOutput.

Most spiders start each parse call with this and then append items and follow-up requests as they discover them.

pub fn into_parts(self) -> (Vec<I>, Vec<Request>)

Consumes the ParseOutput and returns its inner items and requests.

This is mainly used by the runtime, but can also be handy in isolated parsing helpers.

pub fn add_item(&mut self, item: I)

Adds a scraped item to the output.

Use this when the current page produced one structured result that should continue through the configured pipeline chain.

pub fn add_request(&mut self, request: Request)

Adds a new request to be crawled.

Requests emitted here are handed back to the scheduler after the parse step completes.

pub fn add_items(&mut self, items: impl IntoIterator<Item = I>)

Adds multiple scraped items to the output.

pub fn add_requests(&mut self, requests: impl IntoIterator<Item = Request>)

Adds multiple new requests to be crawled.
