Enum uucore::backup_control::BackupError

pub enum BackupError {
    InvalidArgument(String, String),
    AmbiguousArgument(String, String),
    BackupImpossible(),
}

Backup error types.

Errors are currently raised by determine_backup_mode only. All errors are implemented as [UCustomError] for uniform handling across utilities.

Variants

InvalidArgument(String, String)

An invalid argument (e.g. ‘foo’) was given as backup type. First parameter is the argument, second is the arguments origin (CLI or ENV-var)

Tuple Fields of InvalidArgument

0: String1: String

AmbiguousArgument(String, String)

An ambiguous argument (e.g. ‘n’) was given as backup type. First parameter is the argument, second is the arguments origin (CLI or ENV-var)

Tuple Fields of AmbiguousArgument

0: String1: String

BackupImpossible()

Currently unused

Trait Implementations

impl Debug for BackupError

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

Formats the value using the given formatter.

impl Display for BackupError

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

Formats the value using the given formatter.

impl Error for BackupError

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

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

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

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

Returns a stack backtrace, if available, of where this error occurred.

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
