Practical overview
When it fits
Use it when a Rust application needs PDF parsing or broader PDF operations, particularly when an AI or RAG pipeline benefits from chunks that retain document structure and source-page context.
Who it is for
- Rust developers adding PDF extraction or manipulation to an application.
- Teams building document-ingestion and RAG pipelines that need structured PDF chunks before embedding or retrieval.
Documented uses
- Extract text and structural metadata from PDFs.
- Prepare PDF content as chunks with page, heading, element and token information for downstream retrieval workflows.
- Generate, modify, combine or validate PDFs within a Rust application.
Requirements & limits
The repository identifies the project as open source under the MIT license.
- The library prepares content for downstream AI workflows but does not include built-in machine learning or generate embeddings.
- Chunk output can carry page numbers, bounding boxes, element types, heading context and token estimates.
- JSON serialization of chunks requires the
semanticfeature. - PDF rasterization is not included and requires a separate renderer.
Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.
Extract structure-aware chunks from a PDF
Use the library's parser to produce PDF chunks with contextual metadata for downstream processing.
Before you start
- Rust 1.88 or later
- The oxidize-pdf crate
- A PDF file to process
Steps
Add
oxidize-pdf = "5.4.2"to the Rust project's dependencies.Open the file with
PdfDocument::open("document.pdf")?.Call
doc.rag_chunks()?to obtain the chunks.Use fields such as
full_text,page_numbers,element_types,heading_contextandtoken_estimatein the next processing stage.
Expected outcome
A collection of PDF chunks with text and structure-related metadata, ready for application-specific downstream processing.
Guide limitations
- The library does not include a built-in machine-learning component or perform embedding generation.
- Page rasterization is not provided; bitmap output requires a separate renderer.
