}

One element of a document, physical or logical.

Variants

Header

The %PDF-x.y header.

Fields

version: (u8, u8)

span: Span

IndirectObject

One indirect object.

Fields

r: ObjRef

object: Object

span: Span

Span of N G obj … endobj in the file. For objects stored in an object stream this is the container stream object’s span.

in_objstm: Option<(ObjRef, Span)>

For objects inside an object stream: the container’s reference and this object’s byte range within the decoded stream data.

XrefSection

One cross-reference section (table or stream).

Fields

kind: XrefKind

span: Span

entries: usize

Trailer

The trailer: the merged trailer dictionary plus the byte range of the newest trailer region (classic trailer << … >>, or the newest cross-reference stream object when no classic trailer exists). The dict is the MERGED trailer dictionary (keys from newer sections win), while span covers only the newest trailer region — so unlike other physical elements, re-parsing the bytes at span does not reproduce dict.

Fields

dict: Dict

span: Span

StartXref

The startxref keyword and its offset operand.

Fields

offset: u64

span: Span

Eof

The %%EOF marker.

Fields

span: Span

Page

One page (logical).

Fields

index: usize

r: ObjRef

Font

One font referenced from a page’s resources.

Fields

page: Option<usize>

r: ObjRef

subtype: Name

base_font: Option<Name>

Image

One image XObject referenced from a page’s resources.

Fields

page: Option<usize>

r: ObjRef

width: u32

height: u32

Annotation

One annotation on a page.

Fields

page: usize

r: ObjRef

subtype: Name

ContentOp

One content-stream operator of a page.

Fields

page: usize

op: Op

span_in_content: Span

Byte range within the page’s decoded, concatenated content.

Trait Implementations
