Struct XrefTable 

pub struct XrefTable {
    pub entries: HashMap<u32, XrefEntry>,
    pub trailer: Dict,
}

A parsed cross-reference table + trailer dict.

Fields

entries: HashMap<u32, XrefEntry>

Object number → entry. Sparse — a 50-object PDF doesn’t need 50 vec slots if some are never referenced.

trailer: Dict

The trailer dictionary that follows the xref subsection list. Carries /Size, /Root, optionally /Info, /Prev, /ID.

Implementations

impl XrefTable

pub fn offset_of(&self, id: ObjectId) -> Option<u64>

Look up the byte offset of an object by id. None if the id doesn’t appear in the xref or its slot is Free / Compressed (the reader can’t yet resolve compressed objects).

pub fn root(&self) -> Result<ObjectId, PdfError>

Walk the trailer for the /Root reference. Returns PdfError::Other when missing — every conforming PDF must carry one (§7.5.5 Table 15).

pub fn info(&self) -> Option<ObjectId>

Optional /Info reference from the trailer. None when the PDF has no document-level info dict.
