Struct Message

Source
pub struct Message<'a> {
    pub header: Header,
    pub question: Vec<Question>,
    pub answer: Vec<Resource<'a>>,
    pub authority: Vec<Resource<'a>>,
    pub additional: Vec<Resource<'a>>,
}
Expand description

Represents a DNS message.

Fields§

§header: Header

Describes the content of the remainder of the message.

§question: Vec<Question>

Carries the question of query type messages.

§answer: Vec<Resource<'a>>

Resource records that answer the query

§authority: Vec<Resource<'a>>

Resource records that point to an authoritative name server

§additional: Vec<Resource<'a>>

Resource records that relate to the query, but are not strictly answers for the question.

Implementations§

Source§

impl<'a> Message<'a>

Source

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

Constructs a new Message with a random id value.

Source

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

Constructs a new Message with the given id value.

Source

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

Decodes a message from a series of bytes.

Source

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.

Source

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

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

Source

pub fn records(&self) -> RecordIter<'_>

Returns an iterator over the records in this message.

Source

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

Consumes the message and returns an iterator over its records.
