Functions

func NewDNSHandler

func NewDNSHandler(records *Map) dnsutils.Handler

NewDNSHandler creates a new dns handler instance that stores a/aaaa answers

Types

type Map

type Map sync.Map

Map is like a Go map[string][]net.IP but is safe for concurrent use by multiple goroutines without additional locking or coordination

func (*Map) Delete

func (m *Map) Delete(key string)

Delete deletes the value for a key.

func (*Map) Load

func (m *Map) Load(key string) ([]net.IP, bool)

Load returns the value stored in the map for a key, or nil if no value is present. The ok result indicates whether value was found in the map.

func (*Map) LoadAndDelete

func (m *Map) LoadAndDelete(key string) (value []net.IP, loaded bool)

LoadAndDelete deletes the value for a key, returning the previous value if any. The loaded result reports whether the key was present.

func (*Map) LoadOrStore

func (m *Map) LoadOrStore(key string, value []net.IP) ([]net.IP, bool)

LoadOrStore returns the existing value for the key if present. Otherwise, it stores and returns the given value. The loaded result is true if the value was loaded, false if stored.

func (*Map) Range

func (m *Map) Range(f func(key string, value []net.IP) bool)

Range calls f sequentially for each key and value present in the map. If f returns false, range stops the iteration.

Range does not necessarily correspond to any consistent snapshot of the Map's contents: no key will be visited more than once, but if the value for any key is stored or deleted concurrently, Range may reflect any mapping for that key from any point during the Range call.

Range may be O(N) with the number of elements in the map even if f returns false after a constant number of calls.

func (*Map) Store

func (m *Map) Store(key string, value []net.IP)

Store sets the value for a key.
