workflows.WithTaskSpanResult[Result any](
    ctx context.Context,
    name string,
    f func(ctx context.Context) (Result, error),
) (Result, error)
Wrap a function with a tracing span using the current runner’s tracer and return the function result. WithTaskSpanResult is an alias for WithSpanResult. Use it inside a task Execute method. If the context is not a task execution context, the function runs without creating a span.
