Struct LocalIO

#[non_exhaustive]
pub struct LocalIO {}

Filesystem and process tree local IO implementation.

Implementations

impl LocalIO

pub fn new() -> Self

Construct LocalIO instance

Currently there are no internal members in LocalIO, but for stability into the future I’d still recommend using this method in case a need for state is found.

Trait Implementations

impl Default for LocalIO

fn default() -> Self

Returns the “default value” for a type.

impl IO for LocalIO

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
