Implementations

impl Open

pub fn keyed(&mut self) -> Option<&mut Keyed>

pub fn is_keyed(&self) -> bool

pub fn read(&mut self, fixed_len: usize) -> Result<Record>

pub fn write(&mut self, bytes: &[u8]) -> Result<()>

pub fn print( &mut self, before: Option<Move>, line: &str, after: Option<Move>, ) -> Result<()>

Writes a line to a text DD where a printer would put it: after before, over a line not yet ended when nothing moved the paper (after a carriage return, unless one of the two is blank), then after. The first line of the DD takes one line of before as its own start, as a printer at the top of a form prints a single-spaced first line on line 1.

pub fn close(self) -> Result<()>
