Breaking Changes

  • The minimal required Rust version is now 1.65. (#160)
  • The random feature has been dropped in favour of using rand. (#204)
  • The generic octets foundation has been moved to a new crate octseq and completely revamped with Generic Associated Types stabilized in Rust 1.65. This required changes all over the code but, hopefully, should result in relatively few changes when using the crate. (#160)
  • The range, slice, and split methods on the domain name types have changed. They have been merge into a single method taking ranges – except for those on Dname that require type changes. The split methods now take references and don’t change self anymore. (#160)
  • The Parse, Compose, and Scan traits have been demoted to mere extension traits for foreign types (primarily the built-in integers, so that you can do things like u16::parse). All other types now simply have methods matching the patterns. Where generics are necessary, dedicated traits have been added. E.g., there now are ParseRecordData and ComposeRecordData traits that are implemented by all record data types. (#160)
  • The Deref and DerefMut impls have been removed for most types that had them to follow guidance that they are exclusively for use by pointer types – which none of them are. len and is_empty methods have been added where appropriate, additional methods may be added. (#205)
  • Various functions and methods of the tsig module now expect the current time as an argument to allow use of the module in a no-std environment. (#152)
  • Parsing of representation format and zonefiles has been completely re-written. (#142, based on work in #109 by Martin Fischer)
  • All types that wrap an octets sequence only now allow unsized octets sequence types. They all have an associated function from_slice to create a reference to a value wrapping an (unsized) octets slice and method for_slice that converts a &self into such a reference. Where the latter already existed but returned a value wrapping a &[u8] (e.g., Dname<_> and Message<_>, the return type has changed accordingly. (#168)
  • Removed CharStr::from_bytes. Use CharStr::from_octets instead. (#168)
  • Message::from_octets now returns a new error type ShortMessage. (#168)
  • Dropped Deref impls for Dname<_>, RelativeDname<_>. (#168)
  • Renamed opt::KeyTag::new to opt::KeyTag::from_octets. (#168)
  • Renamed rdata::Txt::try_from_slice to build_from_slice. (#168)
  • The new method of the following record data types now check whether the wire format representation of the record data is too long and thus returns a result: Tsig<_, _>, Dnskey<_>, Rrsig<_, _>, Ds<_>, Cdnskey<_>, Cds<_>. (#169)
  • The new function for rdata::Null<_> has been replaced with a from_octets and from_slice pair. The Deref impl was removed. (#169)
  • The rdata::svcb module has been refactored to work in the same way as other type-length-value constructs. The names of types, methods, and functions have changed both to match the usual nomenclature as well as to match the terms used in the SVCB draft. (#176)
  • The base::iana::SvcbParamKey type has been renamed to SvcParamKey to match the terms used in the SVCB draft. (#176)
  • The TcpKeepalive option has been changed to use an Option<u16> as its data and allow for an empty option in accordance with the RFC. (#185)
  • Renamed the sub-modules of rdata that contain record data types to use a name derived from their content rather than their RFC number – with the exception of rdata::rfc1035. (#189)
  • Renamed the sub-modules of base::opt that contain option data types to use short-hand names rather than their RFC number. (#190)
  • TTL values are now using a newtype base::record::Ttl that wraps the raw u32 and improves conversions. (#202 by @CrabNejonas)
  • Changes all option data types to ensure their wire format is at most 65,535 octets long. This requires changing the signatures of some creator functions. Their naming scheme and signatures are also changed to follow the pattern established with record data. (#193)
  • Renamed UnknownOptData::from_octets to new and return a result. (#193)
  • Completely redesigns DNS cookie options, adding support for standard server cookies introduced in RFC 9018. (#193)
  • Change the type of ExtendedError’s text to Str<Octs> and change the return type of set_text to (). (#193)
  • Changed the type TcpKeepalive’s content to a newtype IdleTimeout to make it easier to convert to and from durations. (#193)
  • Changes Padding to just contain the padding octets and drop PaddingMode. Instead, the methods on OptBuilder should be used to add padding. (#193)

New

  • Display impls are now available for all EDNS0 options. (#157)
  • Adds a FromStr implementation and related functions to RelativeDname. (#177)
  • Add a Debug impl to base::message::Message so it can be unwrapped etc. (#199)
  • New methods make_canonical on Dname and RelativeDname that convert the name into its canonical, i.e., lowercase form. Similarly, new methods ToDname::to_canonical_dname and ToRelativeDname::to_canonical_relative_dname that produce new
    canonical names. (#200)
  • Added a MAX_LEN constant to various types that wrap length-limited octets sequences. (#201 by @CrabNejonas)
