What?
Port the telemetry stack (
libdd-telemetry,libdd-data-pipeline) to compile and run onwasm32-unknown-unknown.TelemetryWorker,TelemetryWorkerHandle, andTelemetryClientbecome generic over a capability bundleC: HttpClientCapability + SleepCapability; native call sites pin toNativeCapabilities.Why?
Telemetry was previously hard-gated behind
#[cfg(not(target_arch = "wasm32"))]and was a no-op on that target for theTraceExporter.How?
tokio::timecall (sleep, timeout) is replaced by atokio::select!race against<C as SleepCapability>::new().sleep(…), which resolves tosetTimeouton wasm.std::timereplaced byweb-time(Performance.now()/Date.now()on wasm, re-exportsstd::timeon native).tokio::sync::Notify-based async path alongside the existing nativeCondvarsync path.MockClient/file-endpoint logic inhttp_client.rsis deleted and ported toNativeCapabilitiesinlibdd-capabilities-impl.Additional Notes
TelemetryClientBuilder::buildnow returnsResult(was panicking on missing fields) — Rust API break.TelemetryClient::startis now sync viatry_send_msg— Rust API break.typealias pinned toNativeCapabilities.
