DcsvIo.D2.Headers.Common

Cross-transport D2 wire-protocol headers — entries with applicability count ≥ 2 (headers that appear identically on multiple transports). Codegen-emitted from the headers contract spec via DcsvIo.D2.Headers.SourceGen (filtered with applicability.Length >= 2). Mirrors the TypeScript package @dcsv-io/d2-headers-common at byte-equal wire values; parity is asserted by shared contract tests.

Install

dotnet add package DcsvIo.D2.Headers.Common

Public API

Member Type Purpose
CommonHeaders.PROPAGATED_CONTEXT const string "x-d2-context" Base64url-of-JSON propagated context envelope (HTTP + gRPC + AMQP)
CommonHeaders.TRACEPARENT const string "traceparent" W3C Trace Context (HTTP + gRPC + AMQP)
CommonHeaders.TRACESTATE const string "tracestate" W3C tracestate (HTTP + gRPC + AMQP)
CommonHeaders.AllCommonHeaders IReadOnlyList<string> All wire values in constName order — useful for cross-spec consistency tests

(Catalog is codegen-emitted; the table above lists today's three cross-transport entries. New cross-transport entries appear here automatically when added to the spec.)

When to reach for this catalog

Use DcsvIo.D2.Headers.Common when the consumer is transport-agnostic — e.g. a tracing utility that handles traceparent / tracestate regardless of whether the request arrived over HTTP, gRPC, or AMQP. Transport-specific consumers should reach for DcsvIo.D2.Headers.Http, DcsvIo.D2.Headers.Amqp, or DcsvIo.D2.Headers.Grpc instead — those catalogs include the cross-transport entries inline at identical wire values, so a single using covers everything that transport's pipeline can encounter.

Spec contract

The headers contract spec is the single source of truth. Cross-transport entries appear in CommonHeaders and every per-transport catalog whose applicability array contains the relevant transport, all at identical wire values (codegen-guaranteed and verified by header catalog consistency tests).
