pub struct BasicKind;

The no-fetch crawler kind whose execution hands requests directly to handlers.

Trait Implementations

impl Clone for BasicKind

fn clone(&self) -> BasicKind

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for BasicKind

impl CrawlerKind for BasicKind

type Context = BasicContext

The context passed to user handlers and lifecycle hooks.

fn execute<'a>( &'a self, env: RequestEnv<'a>, ) -> Pin<Box<dyn Future<Output = Result<BasicContext, CrawlError>> + Send + 'a>>

Executes one request attempt and constructs its handler context.

fn cleanup( &self, _outcome: RequestOutcome<BasicContext>, ) -> Pin<Box<dyn Future<Output = Result<(), CrawlError>> + Send + '_>>

Runs after every attempt concludes, regardless of its outcome.

fn start<'a>( &'a self, env: &'a CrawlerEnv, ) -> Pin<Box<dyn Future<Output = Result<(), CrawlError>> + Send + 'a>>

Runs once before the crawler fetches any request.

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

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

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.

fn stop<'a>( &'a self, env: &'a CrawlerEnv, ) -> Pin<Box<dyn Future<Output = Result<(), CrawlError>> + Send + 'a>>

Runs once when crawler shutdown begins.

impl Debug for BasicKind

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for BasicKind

fn default() -> BasicKind

Returns the “default value” for a type.
