Types

type Version

type Version struct {
	Major uint16 `json:"major,omitempty"`
	Minor uint16 `json:"minor,omitempty"`
	Patch uint16 `json:"patch,omitempty"`
}

Version is a protocol or a runtime version.

func FromU64

func FromU64(v uint64) Version

FromU64 returns the version from platform-dependent uint64.

func (Version) MajorMinor

func (v Version) MajorMinor() Version

MajorMinor extracts major and minor segments of the Version only.

This is useful for comparing protocol version since the patch segment can be ignored.

func (Version) String

func (v Version) String() string

String returns the protocol version as a string.

func (Version) ToU64

func (v Version) ToU64() uint64

ToU64 returns the version as platform-dependent uint64.
