View on GitHubPure Rust PDF library for AI/RAG: structure-aware chunking, no ML, no C deps.
Pure Rust PDF toolkit whose headline feature is structure-aware RAG chunking: each chunk carries pages, bounding boxes, element types, heading context and token estimates, with no ML or C dependencies. Also parses, generates, encrypts and validates PDFs in one crate.
Use Cases
