Net.DNSBase.RData.SVCB.SPV

Description

One KnownSVCParamValue instance per standardised service parameter key. Each type corresponds to a SVCParamKey from the IANA registry and carries the value payload for that key in a form suited to the application that consumes it (a port as Word16, address hints as a NonEmpty of IPv4 / IPv6, and so on).

An unknown key falls through to OpaqueSPV, which preserves the raw wire bytes. Applications register additional typed values at runtime via extendRRwithType on the SVCB or HTTPS RR type — see Net.DNSBase.Extensible for a worked example.

Documentation

data SPV_mandatory where Source #

The mandatory service parameter (RFC 9460 section 8) — the set of additional SVCParamKey codes a client must recognise to make sense of this RR, on top of any keys that are automatically mandatory for the application protocol. A client that does not understand all the listed keys must ignore the RR.

The set may not be empty on the wire (an empty list is encoded as the parameter being absent) and may hold at most 32767 keys. The constructor is not exported; build instances via fromNonEmptyList or by combining values with their Semigroup instance.

Bundled Patterns

pattern SPV_MANDATORY	One-way pattern exposing the underlying key set for lookups. Construction is available only via `fromNonEmptyList` or via the `Semigroup` instance.
Fields :: Set SVCParamKey The keys as a `Set` -> SPV_mandatory

Together with SPV_ndalpn it defines the SVCB ALPN set: by default the scheme's protocol is implicitly included, and SPV_ndalpn suppresses that default.

The docpath service parameter (RFC 9953 section 8.2) — the absolute path to the DNS-over-CoAP (DoC) resource at this service endpoint, represented as a list of path segments. An empty list denotes the root path "/" (on the wire: a zero-length SvcParamValue).

Each segment is 1..255 octets per the RFC ABNF; the wire-form decoder rejects zero-length segments. Presentation form is a comma-separated list of segments using the standard RFC 9460 Appendix A.1 quoting and escaping rules, identical to those of SPV_alpn.

newtype SPV_tlsgroups Source #

The tls-supported-groups service parameter (draft-ietf-tls-key-share-prediction-04 section 5) — a non-empty list of TLS Named Group codepoints (the IANA TLS Supported Groups registry) that the service supports. Clients can use this hint to predict an acceptable key share, reducing the chance of a HelloRetryRequest round-trip.

The wire form is a non-empty sequence of 16-bit codepoints in network byte order; the decoder rejects an empty value. The presentation form is a comma-separated list of decimal integers and forbids zone-file escape sequences (per the draft). Duplicates are flagged as a syntax error by the specification but are not currently rejected by either the encoder or the decoder — callers are expected to feed in a duplicate-free list, in their preferred order (the spec does not impose canonical ordering on the wire).

The pvd service parameter (draft-ietf-intarea-proxy-config-14 section 7.5) — a value-less flag that announces the host supports Provisioning Domain discovery via the well-known PvD URI. Its presence in an SVCB or HTTPS RR signals that a client MAY fetch PvD Additional Information from https://host/.well-known/pvd. Per the draft, the wire value MUST be empty; the presentation form is just the bare key name with no '='.
