Types

type Answer

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

First two records from the response decoded by the probe, if they are TXT or SOA; other RR can be decoded from "abuf"

func (*Answer) Mname

func (a *Answer) Mname() string

If the type is "SOA" this will have the original or primary domain name.

func (*Answer) Name

func (a *Answer) Name() string

Domain name.

func (*Answer) Rdata

func (a *Answer) Rdata() []string

If the type is "TXT" this will have the value of that record.

func (*Answer) Rname

func (a *Answer) Rname() string

If the type is "SOA" this will have the mailbox.

func (*Answer) Serial

func (a *Answer) Serial() int

If the type is "SOA" this will have the zone serial number.

func (*Answer) Ttl

func (a *Answer) Ttl() int

If the type is "SOA" this will have the time to live.

func (*Answer) Type

func (a *Answer) Type() string

Resource record type ("SOA" or "TXT").

func (*Answer) UnmarshalJSON

func (a *Answer) UnmarshalJSON(b []byte) error

type Error

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

Error message.

func (*Error) Getaddrinfo

func (e *Error) Getaddrinfo() string

Error message.

func (*Error) Timeout

type Result

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

Response from the DNS server.

func (*Result) Abuf

func (r *Result) Abuf() string

Answer payload buffer from the server, UU encoded.

func (*Result) Ancount

func (r *Result) Ancount() int

Answer count.

func (*Result) Answers

func (r *Result) Answers() []*Answer

First two records from the response decoded by the probe, if they are TXT or SOA; other RR can be decoded from Abuf() using UnpackAbuf().

func (*Result) Arcount

func (r *Result) Arcount() int

Additional record count.

func (*Result) Id

func (r *Result) Id() int

Query ID.

func (r *Result) Qdcount() int

Number of queries.

func (*Result) Rt

func (r *Result) Rt() float64

Response time in milli seconds (optional).

func (*Result) Size

func (r *Result) Size() int

Response size (optional).

func (*Result) SrcAddr

func (*Result) Submax

func (r *Result) Submax() int

Total number of results within a group (optional).

func (*Result) UnmarshalJSON

func (r *Result) UnmarshalJSON(b []byte) error

func (*Result) UnpackAbuf

func (r *Result) UnpackAbuf() (*mdns.Msg, error)

Decode the Abuf(), returns a *Msg from the github.com/miekg/dns package or nil on error or if Abuf() is empty.

type Resultset

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

func (*Resultset) Af

func (r *Resultset) Af() int
