Enum Error

pub enum Error {
    ParseVersionComponentError(ParseIntError, String),
    DotMissing,
    FileNameMissing,
    FileNameToStrError,
    PathFileNameError,
    NoExecutableFound(RequestedVersion),
    IllegalArgument(PathBuf, String),
}

Error enum for the entire crate.

Variants

ParseVersionComponentError(ParseIntError, String)

Parsing a digit component from a string fails.

DotMissing

String parsing fails due to . missing.

FileNameMissing

A Path lacks a file name when it is required.

FileNameToStrError

A file name cannot be converted to a string.

PathFileNameError

A file name is not structured appropriately.

NoExecutableFound(RequestedVersion)

No Python executable could be found based on the constraints provided.

IllegalArgument(PathBuf, String)

An illegal combination of CLI flags are provided.

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)>

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 PartialEq for Error

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

Tests for self and other values to be equal, and is used by ==.

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

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