Enum Error

#[non_exhaustive]
pub enum Error {
    Exec(ExecError),
    Wait(WaitError),
    Output(OutputError),
    Conversion(OutputConversionError),
}

An error produced by a Command failure.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Exec(ExecError)

An execution failure, when a Command fails to start or Child::wait.

Wait(WaitError)

A failure to wait for a Command.

See: Child::wait.

Output(OutputError)

An output failure, when a Command fails by returning a non-zero exit code (or in other cases, when custom validation logic is supplied in methods like CommandExt::output_checked_with).

Note that this is also raised when non-capturing methods like CommandExt::status_checked fail.

Conversion(OutputConversionError)

An output conversion error, when Output fails to convert to a custom format as requested by methods like CommandExt::output_checked_utf8.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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>)
