Methods

impl<'a> Message<'a>

[−]

pub fn new() -> Message<'a>

[−]

Constructs a new Message with a random id value.

pub fn with_id(id: u16) -> Message<'a>

[−]

Constructs a new Message with the given id value.

pub fn decode(data: &[u8]) -> Result<Message, DecodeError>

[−]

Decodes a message from a series of bytes.

pub fn encode<'buf>(     &self,     buf: &'buf mut [u8] ) -> Result<&'buf [u8], EncodeError>

[−]

Encodes a message to a series of bytes. On success, returns a subslice of the given buffer containing only the encoded message bytes.

pub fn get_error(&self) -> Result<(), DnsError>

[−]

Returns a DnsError if the message response code is an error.

Important traits for RecordIter<'a>

impl<'a> Iterator for RecordIter<'a> type Item = &'a Resource<'a>;

pub fn records(&self) -> RecordIter

[−]

Returns an iterator over the records in this message.

Important traits for RecordIntoIter<'a>

impl<'a> Iterator for RecordIntoIter<'a> type Item = Resource<'a>;

pub fn into_records(self) -> RecordIntoIter<'a>

[−]

Consumes the message and returns an iterator over its records.
