Struct assert_cmd::stdin::StdInCommand

pub struct StdInCommand<'a> { /* fields omitted */ }

Command that carries the stdin buffer.

Create a StdInCommand through the CommandStdInExt trait.

Examples

use assert_cmd::prelude::*;

use std::process::Command;

let mut cmd = Command::new("cat");
cmd
    .arg("-et");
cmd
    .with_stdin()
    .buffer("42")
    .assert()
    .stdout("42");

Methods

impl<'a> StdInCommand<'a>

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.

Trait Implementations

impl<'c> OutputAssertExt for &'c mut StdInCommand<'c>

fn assert(self) -> Assert

Wrap with an interface for that provides assertions on the [Output].

impl<'c, 'a> OutputOkExt for &'c mut StdInCommand<'a>

fn ok(self) -> OutputResult

Convert an [Output][Output] to an [OutputResult][OutputResult].

fn unwrap_err(self) -> OutputError

Unwrap a [Output][Output] but with a prettier message than ok().err().unwrap().

fn unwrap(self) -> Output

Unwrap a [Output][Output] but with a prettier message than .ok().unwrap().

impl<'a> Debug for StdInCommand<'a>

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.
