Provided methods

fn locate_xref_offset(&self) -> Result<usize>

Returns the value of startxref (currently only used internally!)

fn read_xref_table_and_trailer(&self) -> Result<(XRefTable, Dictionary)>

Used internally by File, but could also be useful for applications that want to look at the raw PDF objects.
