Struct domain::base::record::ParsedRecord

source ·
pub struct ParsedRecord<'a, Octs: Octets + ?Sized> { /* private fields */ }
Expand description

A raw record parsed from a message.

A value of this type contains the record header and the raw record data. It is mainly used as an intermediary type when turning raw message data into Records.

It allows access to the header only but can be traded for a real record of a specific type of ParseRecordData (i.e., some type that knowns how to parse record data) via the to_record and into_record methods.

Implementations§

source§

impl<'a, Octs: Octets + ?Sized> ParsedRecord<'a, Octs>

source

pub fn new( header: RecordHeader<ParsedDname<&'a Octs>>, data: Parser<'a, Octs>, ) -> Self

Creates a new parsed record from a header and the record data.

The record data is provided via a parser that is positioned at the first byte of the record data.

source

pub fn owner(&self) -> ParsedDname<&'a Octs>

Returns a reference to the owner of the record.

source

pub fn rtype(&self) -> Rtype

Returns the record type of the record.

source

pub fn class(&self) -> Class

Returns the class of the record.

source

pub fn ttl(&self) -> Ttl

Returns the TTL of the record.

source

pub fn rdlen(&self) -> u16

Returns the data length of the record.

source§

impl<'a, Octs: Octets + ?Sized> ParsedRecord<'a, Octs>

source

pub fn to_record<Data>( &self, ) -> Result<Option<Record<ParsedDname<Octs::Range<'_>>, Data>>, ParseError>
where Data: ParseRecordData<'a, Octs>,

Creates a real resource record from the parsed record.

The method is generic over a type that knows how to parse record data via the ParseRecordData trait. The record data is given to this trait for parsing. If the trait feels capable of parsing this type of record (as indicated by the record type) and parsing succeeds, the method returns Ok(Some(_)). It returns Ok(None) if the trait doesn’t know how to parse this particular record type. It returns an error if parsing fails.

source

pub fn into_record<Data>( self, ) -> Result<Option<Record<ParsedDname<Octs::Range<'a>>, Data>>, ParseError>
where Data: ParseRecordData<'a, Octs>,

Trades the parsed record for a real resource record.

The method is generic over a type that knows how to parse record data via the ParseRecordData trait. The record data is given to this trait for parsing. If the trait feels capable of parsing this type of record (as indicated by the record type) and parsing succeeds, the method returns Ok(Some(_)). It returns Ok(None) if the trait doesn’t know how to parse this particular record type. It returns an error if parsing fails.
