Module domain::bits::rdata

Basic resource data handling.

DNS resource records consist of some common data defining the domain name they pertain to, their type and class, and finally record data the format of which depends on the specific record type. As there are currently more than eighty record types, having a giant enum for record data seemed like a bad idea. Instead, resource records are generic over two traits defined by this module. All concrete types implement RecordData. Types that can be parsed out of messages also implement ParsedRecordData. This distinction is only relevant for types that contain and are generic over domain names: for these, parsing is only available if the names use [ParsedDName].

All concrete types shipped with this crate are implemented in the domain::rdata module.

In order to walk over all resource records in a message or work with unknown record types, this module also defines the GenericRecordData type that can deal with all record types but provides only a limited functionality.
