pub fn dup_stdin() -> Result<PipeReader>Expand description
Get a duplicated copy of the current process’s standard input, as a
PipeReader.
Reading directly from this pipe isn’t recommended, because it’s not
synchronized with std::io::stdin. PipeReader implements
Into<Stdio>, so it can be passed directly to Command::stdin. This is
equivalent to Stdio::inherit, though, so it’s usually not necessary
unless you need a collection of different pipes.
