Error enum for the entire crate.

Variants

ParseVersionComponentError(ParseIntError)

String passed to RequestedVersion::from_str or ExactVersion::from_str has an expected digit component that cannot be parsed as an integer.

DotMissing

ExactVersion::from_str is passed a string missing a ..

FileNameMissing

ExactVersion::from_path is given a Path which lacks a file name.

FileNameToStrError

ExactVersion::from_path cannot convert a file name to a string.

PathFileNameError

An unexpected file name was given to ExactVersion::from_path.

NoExecutableFound(RequestedVersion)

No Python executable could be found based on the RequestedVersion.

IllegalArgument(PathBuf, String)

Multiple CLI flags given when the first flag that is expected to be specified on its own.

Implementations

impl Error

pub fn exit_code(&self) -> ExitCode

Returns the appropriate exit code for the error.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

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)>

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

impl PartialEq<Error> for Error

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

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

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

This method tests for !=.
