Struct 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(&mut Box<dyn Read>), ) -> CmdResult

Pipes stdout from the last child in the pipeline to the given function, which runs in the current thread, then waits for all of the children to exit.

If the function returns early, without reading from stdout until the last child exits, then the rest of stdout is automatically read and discarded to allow the child to finish.

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

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