Struct domain::bits::rdata::GenericRecordData

pub struct GenericRecordData<'a> { /* fields omitted */ }

A type for parsing any type of record data.

This type accepts any record type and stores a reference to the plain binary record data in the message. This way, it can later be converted into concrete record data if necessary via the [reparse()] method.

Because the data referenced by a value may contain compressed domain names, transitively building a new message from this data may lead to corrupt messages. To avoid this sort of thing, RFC 3597, ‘Handling of Unknown DNS Resource Record (RR) Types,’ restricted compressed domain names to record types defined in RFC 1035. Accordingly, this types RecordData::compose() implementation treats these types specially and ensures that their names are handles correctly. This may still lead to corrupt messages, however, if the generic record data is obtained from a source not complying with RFC 3597. In general, be wary when re-composing parsed messages unseen.
