Module parallel 

Parallel page-processing utilities.

On native targets: uses rayon for data parallelism. On wasm32: falls back to sequential iteration.

Provides helpers that apply a per-page transformation in parallel across all pages of a document. Designed as a drop-in replacement for the sequential for page in &mut pages { ... } loops in the orchestrator.

Functions

configure_thread_pool

Configure the global rayon thread pool with the given number of threads.

par_extract

Parallel fold — map each page to a value of type T and collect results.

par_map_pages

Apply op to each page in parallel, replacing each page’s content.

par_map_pages_indexed

Apply op to each page in parallel where the closure also receives a zero-based page index.
