Required Methods

fn scrape<'a>( &'a self, url: &'a str, opts: &'a ScrapeOptions, ) -> BoxFuture<'a, Result<Document, ApiError>>

Provided Methods

fn map<'a>( &'a self, _req: &'a MapRequest, ) -> BoxFuture<'a, Result<Vec<MapLink>, ApiError>>

fn crawl<'a>( &'a self, _req: &'a CrawlRequest, _sink: Arc<dyn CrawlSink>, ) -> BoxFuture<'a, Result<(), ApiError>>

整站爬取：抓到一页、出错一页、发现新 URL 时都通过 sink 回报，直到爬完或被取消。

fn search<'a>( &'a self, _req: &'a SearchRequest, ) -> BoxFuture<'a, Result<Value, ApiError>>

/v2/search：返回 Firecrawl 的 data（{ "web": [...] }）。

fn extract<'a>( &'a self, _req: &'a ExtractRequest, ) -> BoxFuture<'a, Result<Value, ApiError>>

/v2/extract：返回提取出的 JSON。

fn supported_formats(&self) -> &'static [&'static str]

引擎支持的 formats；请求了不支持的格式时返回 UNSUPPORTED_OPTION，不悄悄忽略。

fn supports_actions(&self) -> bool

是否支持 actions（需要浏览器渲染）。

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
