Types

type EndpointList

type EndpointList struct {
	// contains filtered or unexported fields
}

EndpointList implements sort.Interface to allow sorting of []common.Endpoint.

func NewEndpointList

func NewEndpointList(endpoints []common.Endpoint) EndpointList

NewEndpointList converts list of common.Endpoint into EndpointList for later sorting.

func (EndpointList) Len

func (p EndpointList) Len() int

func (EndpointList) Less

func (p EndpointList) Less(i, j int) bool

Less compares endpoints using their string representations, implements sort.Interface.

func (EndpointList) List

func (p EndpointList) List() []common.Endpoint

List converts EndpointList into []common.Endpoint.

func (EndpointList) Sort

func (p EndpointList) Sort() EndpointList

Sort is a convinience method to sort EndpointList, returns EndpointList to allow method chaining.

func (EndpointList) Swap

func (p EndpointList) Swap(i, j int)

type EndpointSortGroup

type EndpointSortGroup struct {
	// contains filtered or unexported fields
}

EndpointSortGroup is an auxillary structure for the EndpointList, it contains original endpoint and precalculated string representation which will be used as a sorting criteria by EndpointList.Sort().

type PortRangeSlice

type PortRangeSlice []common.PortRange

PortRangeSlice implements sort.Interface to allow sorting of the []common.PortRange.

func (PortRangeSlice) Len

func (p PortRangeSlice) Len() int

func (PortRangeSlice) Less

func (p PortRangeSlice) Less(i, j int) bool

Less compares port ranges based on difference between low and high port number.

func (PortRangeSlice) Swap

func (p PortRangeSlice) Swap(i, j int)

type RuleSlice

type RuleSlice []common.Rule

RuleSlice implements sort.Interface to allow sorting of the []common.Rule.

func (RuleSlice) Len

func (p RuleSlice) Len() int

func (RuleSlice) Less

func (p RuleSlice) Less(i, j int) bool

func (RuleSlice) Swap

func (p RuleSlice) Swap(i, j int)

type UintSlice

type UintSlice []uint

UintSlice satisfies sort.Interface to allow sorting of a []uint.

func (UintSlice) Len

func (p UintSlice) Len() int

func (UintSlice) Less

func (p UintSlice) Less(i, j int) bool

func (UintSlice) Swap

func (p UintSlice) Swap(i, j int)
