Module error 

Error types for the spider crate.

All fallible operations in scrapling-spider return Result<T>, which is an alias for std::result::Result<T, SpiderError>. The SpiderError enum has a variant for each subsystem (fetch, browser, session, checkpoint, robots.txt, and configuration) so callers can pattern-match on the source of a failure and decide how to handle it – for example, retrying on transient fetch errors while immediately aborting on configuration mistakes.

Both scrapling_fetch::FetchError and scrapling_browser::BrowserError implement Into<SpiderError>, so the ? operator works seamlessly when calling into those crates from spider code.

Enums

SpiderError

The central error type for everything that can go wrong during a crawl.

Type Aliases

Result

A convenience alias so every function in this crate can write Result<T> instead of std::result::Result<T, SpiderError>. This is re-exported from the crate root, so downstream code can use scrapling_spider::Result directly.
