Struct ExtractionEngine 

pub struct ExtractionEngine;

Extraction engine: executes templates against HTML

Uses the scraper crate to evaluate CSS selectors against HTML, applies transformations, and builds structured results.

Implementations

impl ExtractionEngine

pub fn execute(request: &ExtractionRequest) -> Result<ExtractionResult>

Execute an extraction request

Errors

Returns crate::error::PluginError::TemplateValidationError when the embedded template fails validation. Returns crate::error::PluginError::ExtractionError when the request URL or HTML payload is empty, or a region selector matches no elements. Per-region extraction errors are captured as RegionStatus::error entries on the returned ExtractionResult rather than returned directly — only the first hard failure short-circuits the result.

pub fn diagnose( request: &ExtractionRequest, evaluation_scope: &str, ) -> ExtractionDebugInfo
