Struct assert_cmd::StdInCommand

pub struct StdInCommand { /* fields omitted */ }

Command that carries the stdin buffer.

Create a StdInCommand through the CommandStdInExt trait.

Examples

use assert_cmd::prelude::*;

use std::process::Command;

Command::new("cat")
    .with_stdin("42")
    .unwrap();

Methods

impl StdInCommand

pub fn output(&mut self) -> Result<Output>

Executes the command as a child process, waiting for it to finish and collecting all of its output.

By default, stdout and stderr are captured (and used to provide the resulting output). Stdin is not inherited from the parent and any attempt by the child process to read from the stdin stream will result in the stream immediately closing.
