Enum PdfMarkRecord 

#[non_exhaustive]
pub enum PdfMarkRecord {
    DocInfo(DocInfoRecord),
    Outline(OutlineRecord),
    Annotation(AnnotationRecord),
    Dest(DestRecord),
    PageOverride(PageOverrideRecord),
    ViewerPrefs(ViewerPrefsRecord),
    Metadata(MetadataRecord),
    Form(FormRecord),
    Embed(EmbedRecord),
}

One accumulated pdfmark record. Each variant corresponds to a type-tag the interpreter recognises (/DOCINFO, /OUT, /ANN, …). Later phases add variants without disturbing this enum’s external API beyond the new variant itself.

Marked #[non_exhaustive]: cross-crate match sites need a wildcard arm so future type-tags (Tagged PDF, etc.) land additively.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

DocInfo(DocInfoRecord)

/DOCINFO — entries to merge into the PDF Info dictionary.

Outline(OutlineRecord)

/OUT — one bookmark entry, contributing to the document’s outline tree.

Annotation(AnnotationRecord)

/ANN — one page annotation (link, sticky note, free-text, …).

Dest(DestRecord)

/DEST — one named destination contributing to /Names /Dests.

PageOverride(PageOverrideRecord)

/PAGE (single-page override) or /PAGES (document-wide default for keys that aren’t already overridden on a specific page).

ViewerPrefs(ViewerPrefsRecord)

/VIEWERPREFERENCES — catalog-level viewer preferences plus the /PageLayout and /PageMode overrides that live directly on /Catalog rather than nested under /ViewerPreferences.

Metadata(MetadataRecord)

/Metadata — XMP metadata stream attached to /Catalog.

Form(FormRecord)

/FORM — document-level AcroForm dict. Multiple records merge last-wins key-by-key; the /Fields array is implicit (built from /Widget annotations at write time).

Embed(EmbedRecord)

/EMBED — one embedded file attachment. Multiple records accumulate; the writer assembles a /Names /EmbeddedFiles name tree and references it from /Catalog.
