A small Go worker for Quill Cloud

This tutorial shows a complete handler shape for a Go worker. The example validates input, returns transient errors only when appropriate, and logs the task identifier.

package main

import (
  "context"
  "errors"
  "log"
  "time"
)

type Task struct { ID string; Payload map[string]string }

func handle(ctx context.Context, task Task) error {
  if task.Payload["recipient"] == "" { return errors.New("recipient is required") }
  select { case <-ctx.Done(): return ctx.Err(); case <-time.After(25 * time.Millisecond): }
  log.Printf("completed task %s", task.ID)
  return nil
}

func main() {
  task := Task{ID: "task_demo", Payload: map[string]string{"recipient": "dev@example.test"}}
  if err := handle(context.Background(), task); err != nil { log.Fatal(err) }
}
