A ReqParseError is returned from methods which parse a string into a VersionReq. Each enumeration is one of the possible errors that can occur.

Variants

InvalidVersionRequirement

The given version requirement is invalid.

OpAlreadySet

You have already provided an operation, such as =, ~, or ^. Only use one.

InvalidSigil

The sigil you have written is not correct.

VersionComponentsMustBeNumeric

All components of a version must be numeric.

InvalidIdentifier

There was an error parsing an identifier.

MajorVersionRequired

At least a major version is required.

UnimplementedVersionRequirement

An unimplemented version requirement.

DeprecatedVersionRequirement(VersionReq)

This form of requirement is deprecated.

Trait Implementations

fn clone(&self) -> ReqParseError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl PartialEq<ReqParseError> for ReqParseError

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

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

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

This method tests for !=.

impl From<String> for ReqParseError

fn from(other: String) -> ReqParseError

Performs the conversion.

impl Display for ReqParseError

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

Formats the value using the given formatter.

impl Debug for ReqParseError

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

Formats the value using the given formatter.

impl Error for ReqParseError

fn description(&self) -> &str

This method is soft-deprecated.

fn cause(&self) -> Option<&dyn Error>

Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

The lower-level cause of this error, if any.

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.
