Context.Reference<StackFrame | undefined>Context reference for the current captured stack-frame chain for the running fiber.
When to use
Use when writing low-level tracing or diagnostic integrations that need direct access to the stack-frame chain carried by the current fiber.
Details
Effect and Layer tracing use this reference to attach stack-frame information to failures and interruption causes. It is normally managed by tracing APIs rather than provided directly by application code.
