import ( "github.com/hashicorp/terraform/helper/schema" ) func resourceExample() *schema.Resource { return &schema.Resource{ Create: resourceCreate, Read: resourceRead, Update: resourceUpdate, Delete: resourceDelete, Schema: map[string]*schema.Schema{ "example_id": &schema.Schema{ Type: schema.TypeString, Optional: true, }, "example_data": &schema.Schema{ Type: schema.TypeString, Optional: true, }, }, } } func resourceCreate(d *schema.ResourceData, m interface{}) error { // Perform resource creation logic exampleID := "example-ID-123" d.SetId(exampleID) return nil }In this example, the `SetId` method is called in the `resourceCreate` function after creating the resource instance. The value passed to `SetId` is a hard-coded string, but it could also be generated dynamically based on the created resource. Based on the package name and function signature, it appears that this code is written in Go and is using the `github.com.hashicorp.terraform.helper.schema` package.
