Swift Service Context

This package is now a thin compatibility layer. The implementation of ServiceContext moved into swift-distributed-tracing, where the type is named InstrumentationContext. import ServiceContextModule keeps compiling and behaving exactly as it does today, with no code changes required.

New projects, and existing ones that can freely update their code, should depend on swift-distributed-tracing directly and use InstrumentationContext (or Tracing, if they also need spans) instead of adding this package.

ServiceContext is a minimal context propagation container: a value type, propagated through task-local storage, that carries arbitrary key-value pairs across concurrent Swift code.

Dependency

If you already depend on this package, you do not need to change anything.

For new code, depend on swift-distributed-tracing directly instead:

dependencies: [
  .package(url: "https://github.com/apple/swift-distributed-tracing.git", from: "1.0.0")
]

targets: [
    .target(
        name: "MyAwesomeApp",
        dependencies: [
            .product(name: "Tracing", package: "swift-distributed-tracing")
        ]
    )
]

Depend on the Instrumentation product instead of Tracing if you only need context propagation, with no tracing spans.
