Enum Error 

#[non_exhaustive]
pub enum Error {
    CommonError(ParseError<'static>),
    MultibyteDelimiter {
        delimiter: Field,
    },
    MissingOperand,
    InvalidVariableName {
        name: Field,
    },
}

Error in parsing command line arguments

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

CommonError(ParseError<'static>)

An error occurred in the common parser.

MultibyteDelimiter

The delimiter specified by the -d option is multibyte.

Fields

delimiter: Field

MissingOperand

No operand is given.

InvalidVariableName

An operand is not a valid variable name.

Fields

name: Field

Implementations

impl Error

pub fn to_report(&self) -> Report<'_>

Converts this error to a report.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate 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, __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<'a> From<&'a Error> for Report<'a>

fn from(error: &'a Error) -> Self

Converts to this type from the input type.

impl From<ParseError<'static>> for Error

fn from(source: ParseError<'static>) -> Self

Converts to this type from the input type.

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.
