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 UError 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)

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)

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 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, demand: &mut Demand<'a>)

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

Provides type based access to context intended for error reports.

impl PartialEq<BackupError> for BackupError

fn eq(&self, other: &BackupError) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl UError for BackupError

fn code(&self) -> i32

Error code of a custom error.

fn usage(&self) -> bool

Print usage help to a custom error.
