Enum semver::ReqParseError

pub enum ReqParseError {

}

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.
