Library error type. Every variant carries enough context that a user-facing message can be derived without re-running the failing command.

Variants

CommandFailed

A subprocess exited non-zero. stderr is preserved verbatim so the caller can show the underlying tool’s diagnosis.

Fields

cmd: String

status: i32

stderr: String

io: Option<Error>

MissingDependency

The target binary is not on PATH. hint is a copy-pastable fix instruction.

Fields

binary: String

detail: String

hint: Option<String>

io: Option<Error>

Config(ConfigError)

Config file could not be read or written.

NoMatch

The parsed diskutil output did not contain an NTFS volume matching the user’s request.

Fields

pattern: String

ConfirmationMismatch

Confirmation phrase did not match.

Fields

expected: String

actual: String

Cancelled

User pressed Ctrl-C or answered “no” to a confirmation prompt.

InvalidArgument(String)

Argument validation failure (empty label, unknown device, …).

Io(Error)

Underlying I/O error that does not fit into a more specific variant. Kept narrow so ? from std::fs::read_to_string and the like still works.

Serde(String)

Serialization / parsing error (plist, toml, json).

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, __formatter: &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>)

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

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

impl From<ConfigError> for Error

fn from(source: ConfigError) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.
