Struct assert_cmd::OutputError

pub struct OutputError { /* fields omitted */ }

Command error.

Examples

use assert_cmd::prelude::*;

use std::process::Command;

let err = Command::main_binary()
    .unwrap()
    .env("exit", "42")
    .unwrap_err();

Methods

impl OutputError

pub fn new(output: Output) -> Self

Convert std::process::Output into a Fail.

pub fn with_cause<E>(cause: E) -> Self where     E: Into<Error>,

For errors that happen in creating a std::process::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 std::process::Output.

Examples

use assert_cmd::prelude::*;

use std::process::Command;

let err = Command::main_binary()
    .unwrap()
    .env("exit", "42")
    .unwrap_err();
let output = err
    .as_output()
    .unwrap();
assert_eq!(Some(42), output.status.code());

Trait Implementations

impl Fail for OutputError

fn cause(&self) -> Option<&Fail>

Returns a reference to the underlying cause of this failure, if it is an error that wraps other errors.

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

Returns a reference to the Backtrace carried by this failure, if it carries one.

fn context<D>(self, context: D) -> Context<D> where     D: Display + Send + Sync + 'static,

Provides context for this failure.

fn compat(self) -> Compat<Self>

Wraps this failure in a compatibility wrapper that implements std::error::Error.

fn causes(&self) -> Causes

Returns a iterator over the causes of this Fail with itself as the first item and the root_cause as the final item.

fn root_cause(&self) -> &(Fail + 'static)

Returns the "root cause" of this Fail - the last value in the cause chain which does not return an underlying cause.

impl Debug for OutputError

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

Formats the value using the given formatter.

impl Display for OutputError

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

Formats the value using the given formatter.
