Types

type Application

type Application interface {
	Version
	App() string
	Compatible(Application) error
	Before(Application) bool
}

Application defines what is needed to describe a versioned Application.

func NewApplication

func NewApplication(
	app string,
	appSeparator string,
	versionSeparator string,
	major int,
	minor int,
	patch int,
) Application

NewApplication returns a new version

func NewDefaultApplication

func NewDefaultApplication(
	app string,
	major int,
	minor int,
	patch int,
) Application

NewDefaultApplication returns a new version with default separators

type ApplicationParser

type ApplicationParser interface {
	Parse(string) (Application, error)
}

ApplicationParser defines the interface of an ApplicationVersion parser

func NewApplicationParser

func NewApplicationParser(appSeparator string, versionSeparator string) ApplicationParser

NewApplicationParser returns a new parser

func NewDefaultApplicationParser

func NewDefaultApplicationParser() ApplicationParser

NewDefaultApplicationParser returns a new parser with the default separators

type Compatibility

type Compatibility interface {
	// Returns the local version
	Version() Application

	// Returns nil if the provided version is compatible with the local version.
	// This means that the version is connectable and that consensus messages
	// can be made to them.
	Compatible(Application) error

	// Returns nil if the provided version shouldn't be masked. This means that
	// the version is connectable but not compatible. The version is so old that
	// it should just be masked.
	Unmaskable(Application) error

	// Returns nil if the provided version will not be masked by this version.
	WontMask(Application) error

	// Returns when additional masking will occur.
	MaskTime() time.Time
}

Compatibility a utility for checking the compatibility of peer versions

func GetCompatibility

func GetCompatibility(networkID uint32) Compatibility

func NewCompatibility

func NewCompatibility(
	version Application,
