pub fn new() -> Self

Trait Implementations

impl IO for DummyIO

fn run_command( &mut self, _ui: &mut UILock<'_>, _command: String, ) -> Result<(), IOError>

Run a lone command (unrelated from the buffer)

fn run_read_command( &mut self, _ui: &mut UILock<'_>, _command: String, ) -> Result<String, IOError>

Run a read command, collecting stdout to add into buffer

fn run_write_command( &mut self, _ui: &mut UILock<'_>, _command: String, _input: LinesIter<'_>, ) -> Result<usize, IOError>

Run a write command, receiving part of buffer via stdin

fn run_transform_command( &mut self, _ui: &mut UILock<'_>, _command: String, _input: LinesIter<'_>, ) -> Result<String, IOError>

Run a transform command, taking part of buffer via stdin and returning it via stdout.

fn write_file( &mut self, _path: &str, _append: bool, _data: LinesIter<'_>, ) -> Result<usize, IOError>

Normal file write

fn read_file( &mut self, _path: &str, _must_exist: bool, ) -> Result<String, IOError>

Normal file read
