Struct ExecError 

pub struct ExecError { /* private fields */ }

An error from failing to execute a command. Produced by CommandExt.

This is a command that fails to start, rather than a command that exits with a non-zero status or similar, like OutputError.

let mut command = Command::new("echo");
command.arg("puppy doggy");
let displayed: Utf8ProgramAndArgs = (&command).into();
let error = ExecError::new(
    Box::new(displayed),
    std::io::Error::new(
        std::io::ErrorKind::NotFound,
        "File not found (os error 2)"
    ),
);
assert_eq!(
    error.to_string(),
    "Failed to execute `echo`: File not found (os error 2)"
);

Implementations

Trait Implementations

impl Debug for ExecError

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

Formats the value using the given formatter.

impl Display for ExecError

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

impl Error for ExecError

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

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

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

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

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

Provides type-based access to context intended for error reports.

impl From<ExecError> for Error

fn from(error: ExecError) -> Self

Converts to this type from the input type.
