Expand description

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.
