Enum UtilsArgParserError 

pub enum UtilsArgParserError {
    ForbiddenArgument(String, String),
    MissingArgument(String),
    MissingValue(String),
    UnexpectedArgument(String),
    DuplicateArgument(String),
}

Errors associated with parsing and validating arguments.

Variants

ForbiddenArgument(String, String)

Argument ‘{1}’ cannot be used together with argument ‘{0}’.

MissingArgument(String)

Argument ‘{0}’ required, but not found.

MissingValue(String)

The argument ‘{0}’ requires a value, but none was supplied.

UnexpectedArgument(String)

DuplicateArgument(String)

The argument ‘{0}’ was provided more than once.

Trait Implementations

impl Debug for UtilsArgParserError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for UtilsArgParserError

fn fmt(&self, formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for UtilsArgParserError

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 UtilsArgParserError

fn eq(&self, other: &UtilsArgParserError) -> 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.
