 * @example
 * Use a bare-bones client and the command you need to make an API call.
 * ```javascript

 * // const { OpenSearchServerlessClient, GetIndexCommand } = require("@aws-sdk/client-opensearchserverless"); // CommonJS import
 * // import type { OpenSearchServerlessClientConfig } from "@aws-sdk/client-opensearchserverless";
 * const config = {}; // type is OpenSearchServerlessClientConfig
 * const client = new OpenSearchServerlessClient(config);
 * const input = { // GetIndexRequest
 *   id: "STRING_VALUE", // required
 *   indexName: "STRING_VALUE", // required
 * };
 * const command = new GetIndexCommand(input);
 * const response = await client.send(command);
 * // { // GetIndexResponse
 * //   indexSchema: "DOCUMENT_VALUE",
 * // };
 *
 * ```
 *
 * @param GetIndexCommandInput - {@link GetIndexCommandInput}
 * @returns {@link GetIndexCommandOutput}
 * @see {@link GetIndexCommandInput} for command's `input` shape.
 * @see {@link GetIndexCommandOutput} for command's `response` shape.
 * @see {@link OpenSearchServerlessClientResolvedConfig | config} for OpenSearchServerlessClient's `config` shape.

 * @throws {@link InternalServerException} (server fault)
 *  <p>Thrown when an error internal to the service occurs while processing a request.</p>
 *
 * @throws {@link ResourceNotFoundException} (client fault)
 *  <p>Thrown when accessing or deleting a resource that does not exist.</p>
 *
 * @throws {@link ValidationException} (client fault)
