unparser-shared

Shared plumbing for the unpdf, undoc and unhwp document-extraction family.

What's here today

• ffi — thread-local last-error storage and a panic guard for a C ABI that returns sentinels rather than Result.
• kind — the error-kind numbering the family already shares, and the bands that keep future reasons from colliding.
• scaffold — macros that assemble a C entry point out of the two primitives above.
• refine (opt-in feature) — a lossless, idempotent markdown shape-refinement pass: table shape normalization, ordered-list renumbering, link/image path normalization, frontmatter normalization, and section anchors.
• ai (opt-in feature, native only) — VLM-based image understanding (structured extraction with merged-cell tables, or a context-aware description — judged per image in one call) and AI-assisted markdown refine. Both are inert until a caller supplies an AiConfig; neither touches the network otherwise. Not available on wasm32-unknown-unknown (its HTTP client does not target wasm).

ffi/kind/scaffold are always compiled and have zero dependencies — three published cdylibs link this crate statically, so a dependency here is a dependency in all of them. refine and ai are opt-in and bring their own dependencies only when enabled (pulldown-cmark/pulldown-cmark-to-cmark for refine; ureq/serde/serde_json/base64/ thiserror for ai).

See docs.rs for the current API.
