Module item 

Item traits and parse-time output helpers.

ParseOutput is the async sink carried by a spider’s parse context. Spiders typically use it indirectly through ParseContext helpers such as cx.add_item(...) and cx.add_request(...), while the runtime uses it to stream scraped items and follow-up requests as they are discovered.

Example

use spider_util::item::{ScrapedItem, ParseOutput};

#[spider_macro::scraped_item]
struct Article {
    title: String,
    content: String,
}

// In your spider's parse method:
// output.add_item(Article { title: "...", content: "..." }).await?;
// output.add_request(request).await?;

ParseOutput intentionally hides the runtime transport details. The crawler can backpressure parsing internally while spider code continues to use familiar add_* methods.
