Module context 

Available on crate feature otel only.

OpenTelemetry context propagation helpers for async boundaries.

The SDK uses tokio::spawn in run(). Those spawned futures are wrapped with FutureExt::with_context() so the caller’s OTel context is re-attached on every poll, surviving task migration across tokio worker threads. run_turn() executes directly in the caller task and therefore does not need an extra spawn propagation hop.

Functions

capture_context

Capture the current OTel context for propagation into a spawned task.

current_with_span_context

Capture the current OTel context and replace the active span.
