pub struct OutputError { /* fields omitted */ }

Command error.

Generally produced by OutputOkExt.

    .unwrap_err();

Implementations

impl OutputError

pub fn new(output: Output) -> Self

Convert Output into an Error.

pub fn with_cause<E>(cause: E) -> Self where
    E: Error + Send + Sync + 'static, 

For errors that happen in creating a Output.

pub fn set_cmd(self, cmd: String) -> Self

Add the command line for additional context.

pub fn set_stdin(self, stdin: Vec<u8>) -> Self

Add the stdin for additional context.

pub fn as_output(&self) -> Option<&Output>

Access the contained Output.

Examples

use assert_cmd::prelude::*;

use std::process::Command;

let err = Command::new("a-command")
    .args(&["--will-fail"])
    .unwrap_err();
let output = err
    .as_output()
    .unwrap();
assert_eq!(Some(42), output.status.code());

Trait Implementations

pub fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for OutputError

pub fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for OutputError

pub fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

pub fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

pub fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

pub fn cause(&self) -> Option<&dyn Error>

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
