Function SendWithContext

go/base/context.go:1047–1054

SendWithContext attempts to send a value to a channel, but returns early if the context is cancelled. This prevents goroutine deadlocks when the channel receiver has exited due to an error. Use this instead of bare channel sends (ch <- val) in goroutines to ensure proper cleanup when the migration

(ctx context.Context, ch chan<- T, val T)

//	    return err  // context was cancelled
//	}
func SendWithContext[T any](ctx context.Context, ch chan<- T, val T) error {
	select {
	case ch <- val:
		return nil
	case <-ctx.Done():
		return ctx.Err()
	}
}
