Struct cmd_lib::FunChildren

pub struct FunChildren { /* private fields */ }

Representation of running or exited children processes with output, connected with pipes optionally.

Calling spawn_with_output! macro will return Result<FunChildren>

Implementations

impl FunChildren

pub fn wait_with_all(&mut self) -> (CmdResult, String, String)

Waits for the children processes to exit completely, returning the command result, stdout content string and stderr content string.

pub fn wait_with_output(&mut self) -> FunResult

Waits for the children processes to exit completely, returning the stdout output.

pub fn wait_with_raw_output(&mut self, buf: &mut Vec<u8>) -> CmdResult

Waits for the children processes to exit completely, and read all bytes from stdout into buf.

pub fn wait_with_pipe(&mut self, f: &mut dyn FnMut(Box<dyn Read>)) -> CmdResult

Waits for the children processes to exit completely, pipe content will be processed by provided function.

pub fn pids(&self) -> Vec<u32>

Returns the OS-assigned process identifiers associated with these children processes.
