Struct domain::base::rdata::UnknownRecordData

pub struct UnknownRecordData<Octets> { /* private fields */ }

A type for parsing any type of record data.

This type accepts any record type and stores the plain, unparsed record data as an octets sequence.

Because some record types allow compressed domain names in their record data, this type cannot be used safely with these record types. For these record types, the structure of the content needs to be known.

RFC 3597 limits the types for which compressed names are allowed in the record data to those defined in RFC 1035 itself. Specific types for all these record types exist in domain::rdata::rfc1035.

Ultimately, you should only use this type for record types for which there is no implementation available in this crate. The two types AllRecordData and MasterRecordData provide a convenient way to always use the correct record data type.

Implementations

impl<Octets> UnknownRecordData<Octets>

pub fn from_octets(rtype: Rtype, data: Octets) -> Self

Creates generic record data from a bytes value contain the data.

pub fn rtype(&self) -> Rtype

Returns the record type this data is for.

pub fn data(&self) -> &Octets

Returns a reference to the record data.

impl UnknownRecordData<Bytes>

pub fn scan<C: CharSource>(
    rtype: Rtype,
    scanner: &mut Scanner<C>
) -> Result<Self, ScanError>

Scans the record data.

This isn’t implemented via Scan, because we need the record type.
