/**
 * A schema is a format that messages must follow,
 * creating a contract between publisher and subscriber that Pub/Sub will enforce.
 *
 * To get more information about Schema, see:
 *
 * * [API documentation](https://cloud.google.com/pubsub/docs/reference/rest/v1/projects.schemas)
 * * How-to Guides
 *     * [Creating and managing schemas](https://cloud.google.com/pubsub/docs/schemas)
 *
 * ## Example Usage
 *
 * ### Pubsub Schema Basic
 *
 * ```typescript
 * import * as pulumi from "@pulumi/pulumi";
 * import * as gcp from "@pulumi/gcp";
 *
 * const example = new gcp.pubsub.Schema("example", {
 *     name: "example-schema",
 *     type: "AVRO",
 *     definition: `{
 *   "type" : "record",
 *   "name" : "Avro",
 *   "fields" : [
 *     {
 *       "name" : "StringField",
 *       "type" : "string"
 *     },
 *     {
 *       "name" : "IntField",
 *       "type" : "int"
 *     }
 *   ]
 * }
 * `,
 * });
 * ```
 * ### Pubsub Schema Protobuf
 *
 * ```typescript
 * import * as pulumi from "@pulumi/pulumi";
 * import * as gcp from "@pulumi/gcp";
 *
 * const example = new gcp.pubsub.Schema("example", {
 *     name: "example",
 *     type: "PROTOCOL_BUFFER",
 *     definition: `syntax = "proto3";
 * message Results {
 * string message_request = 1;
 * string message_response = 2;
 * string timestamp_request = 3;
 * string timestamp_response = 4;
 * }`,
 * });
 * const exampleTopic = new gcp.pubsub.Topic("example", {
 *     name: "example-topic",
 *     schemaSettings: {
 *         schema: "projects/my-project-name/schemas/example",
 *         encoding: "JSON",
 *     },
 * }, {
 *     dependsOn: [example],
 * });
 * ```
 *
 * ## Import
 *
 * Schema can be imported using any of these accepted formats:
 *
 * * `projects/{{project}}/schemas/{{name}}`
 * * `{{project}}/{{name}}`
 * * `{{name}}`
 *
 * When using the `pulumi import` command, Schema can be imported using one of the formats above. For example:
 *
 * ```sh
 * $ pulumi import gcp:pubsub/schema:Schema default projects/{{project}}/schemas/{{name}}
 * $ pulumi import gcp:pubsub/schema:Schema default {{project}}/{{name}}
 * $ pulumi import gcp:pubsub/schema:Schema default {{name}}
 * ```
