1.20.0 · source§impl From<ChildStdout> for Stdio
impl From<ChildStdout> for Stdio
source§fn from(child: ChildStdout) -> Stdio
fn from(child: ChildStdout) -> Stdio
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");
1.74.0 · source§impl From<OwnedFd> for ChildStdout
Available on Unix only.
impl From<OwnedFd> for ChildStdout
Available on Unix only.
Creates a ChildStdout
from the provided OwnedFd
.
The provided file descriptor must point to a pipe
with the CLOEXEC
flag set.
1.74.0 · source§impl From<OwnedHandle> for ChildStdout
Available on Windows only.
impl From<OwnedHandle> for ChildStdout
Available on Windows only.
Creates a ChildStdout
from the provided OwnedHandle
.
The provided handle must be asynchronous, as reading and writing from and to it is implemented using asynchronous APIs.
