Provided methods

fn is_empty(&self) -> bool[src]

fn locate_start_offset(&self) -> Result<usize>[src]

Returns the offset of the beginning of the file, i.e., where the %PDF-1.5 header is. (currently only used internally!)

fn locate_xref_offset(&self) -> Result<usize>[src]

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

fn read_xref_table_and_trailer(
    &self,
    start_offset: usize
) -> Result<(XRefTable, Dictionary)>[src]

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