1.0.0[][src]Struct boolean_enums::lstd::process::ChildStdout

pub struct ChildStdout { /* fields omitted */ }

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.

[src]

impl From<ChildStdout> for Stdio
1.20.0
[src]

fn from(child: ChildStdout) -> Stdio
[src]

Converts a ChildStdout into a Stdio

Examples

ChildStdout will be converted to Stdio 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");
