//! Helper functions and utilities for extraction operations.
//!
//! This module provides shared utilities used across extraction modules.

use crate::Result;
use crate::plugins::InternalDocumentExtractor;
use std::sync::Arc;

/// Get an extractor from the registry.
///
/// This function acquires the registry read lock and retrieves the appropriate
/// extractor for the given MIME type.
///
/// When the `otel` feature is enabled, the returned extractor is wrapped in an
/// [`InstrumentedExtractor`](crate::plugins::extractor::instrumented::InstrumentedExtractor)
/// that adds tracing spans and metrics automatically.
///
/// # Performance
///
/// RwLock read + HashMap lookup is ~100ns, fast enough without caching.
/// Removed thread-local cache to avoid Tokio work-stealing scheduler issues.
