1.0.0[−][src]Struct std::process::ChildStdout
A handle to a child process's standard output (stdout).
This struct is used in the stdout
field on Child
.
When an instance of ChildStdout
is dropped, the ChildStdout
's
underlying file handle will be closed.

using Stdio::from
under the hood.
use std::process::{Command, Stdio}; let hello = Command::new("echo") .arg("Hello, world!") .stdout(Stdio::piped()) .spawn() .expect("failed echo command"); let reverse = Command::new("rev") .stdin(hello.stdout.unwrap()) // Converted into a Stdio here .output() .expect("failed reverse command"); assert_eq!(reverse.stdout, b"!dlrow ,olleH\n");Run
