Struct std::process::ChildStdin
pub struct ChildStdin { /* fields omitted */ }
A handle to a child process’s standard input (stdin).
This struct is used in the stdin field on Child.
When an instance of ChildStdin is dropped, the ChildStdin’s underlying file handle will be closed. If the child process was blocked on input prior to being dropped, it will become unblocked after dropping.
Trait Implementations
fn as_raw_handle(&self) -> RawHandle
Extracts the raw handle, without taking any ownership.
impl Debug for ChildStdin
fn fmt(&self, f: &mut Formatter<'_>) -> Result
Formats the value using the given formatter. Read more
fn from(child_stdin: ChildStdin) -> OwnedFd
Performs the conversion.
fn from(child_stdin: ChildStdin) -> OwnedHandle
Performs the conversion.
impl From<ChildStdin> for Stdio
fn from(child: ChildStdin) -> Stdio
Converts a ChildStdin into a Stdio
Examples
ChildStdin will be converted to Stdio using Stdio::from under the hood.
use std::process::{Command, Stdio};
let reverse = Command::new("rev")
.stdin(Stdio::piped())
.spawn()
.expect("failed reverse command");
let _echo = Command::new("echo")
.arg("Hello, world!")
.stdout(reverse.stdin.unwrap()) // Converted into a Stdio here
.output()
.expect("failed echo command");
// "!dlrow ,olleH" echoed to consolefn into_raw_fd(self) -> RawFd
