Struct Xref 

pub struct Xref {
    pub trailer: Dict,
    /* private fields */
}

The merged cross-reference table plus the (merged) trailer dictionary.

Fields

trailer: Dict

Merged trailer dictionary; keys from newer sections win.

Implementations

impl Xref

pub fn get(&self, num: u32) -> Option<XrefEntry>

Looks up the entry for object number num.

pub fn newest_section(&self) -> Option<NewestSection>

The file’s newest cross-reference section: its offset and kind, as recorded while the section chain was walked. None when the file was loaded by a whole-file recovery scan, which has no single section to point to.

pub fn merge(&mut self, older: Xref)

Merges an older section into this one. Entries already present win (sections are walked newest to oldest, first-seen wins); trailer keys and the newest-section record already present are kept.

Covers ISO 32000-1 §7.5.6.

pub fn iter(&self) -> impl Iterator<Item = (u32, XrefEntry)> + '_

Iterates all (object number, entry) pairs in unspecified order.

pub fn len(&self) -> usize

Number of entries.

pub fn is_empty(&self) -> bool

Whether the table has no entries.
