Struct BrowserKind 

pub struct BrowserKind<P: BrowserProvider> { /* private fields */ }

Browser fetching behavior used by BrowserCrawler.

Session persistence has explicit ownership semantics. An owned pool is attached to crawler storage, restored in CrawlerKind::start, persisted on PersistState, and persisted once more during CrawlerKind::stop. A shared pool is used for session selection and cookie synchronization only: the sharing owner (for example, a smart kind) must restore and persist it. This prevents double restore and double persistence when kinds share one pool.

Implementations

impl<P: BrowserProvider> BrowserKind<P>

pub fn builder(provider: P) -> BrowserKindBuilder<P>

Starts configuring a browser crawler kind backed by provider.

Trait Implementations

impl<P: BrowserProvider> CrawlerKind for BrowserKind<P>

type Context = BrowserContext

The context passed to user handlers and lifecycle hooks.

fn start<'a>( &'a self, env: &'a CrawlerEnv, ) -> BoxFuture<'a, Result<(), CrawlError>>

Runs once before the crawler fetches any request.

fn execute<'a>( &'a self, env: RequestEnv<'a>, ) -> BoxFuture<'a, Result<Self::Context, CrawlError>>

Executes one request attempt and constructs its handler context.

fn observe(&self, ctx: &Self::Context) -> AttemptObservation

Called once after execute() succeeds; feeds statistics, HandledRequest, and RetryStrategy metadata.

fn cleanup( &self, outcome: RequestOutcome<Self::Context>, ) -> BoxFuture<'_, Result<(), CrawlError>>

Runs after every attempt concludes, regardless of its outcome.

fn stop<'a>( &'a self, _env: &'a CrawlerEnv, ) -> BoxFuture<'a, Result<(), CrawlError>>

Runs once when crawler shutdown begins.

fn before_request<'a>( &'a self, prep: &'a mut RequestPrep, ) -> Pin<Box<dyn Future<Output = Result<(), CrawlError>> + Send + 'a>>

Mutates a request before an attempt executes.

fn after_success<'a>( &'a self, ctx: &'a mut Self::Context, ) -> Pin<Box<dyn Future<Output = Result<(), CrawlError>> + Send + 'a>>

Runs after the user handler succeeds.
