/**
 * <p>Updates a Lambda function's code. If code signing is enabled for the function, the code package must be signed
 *       by a trusted publisher. For more information, see <a href="https://docs.aws.amazon.com/lambda/latest/dg/configuration-trustedcode.html">Configuring code signing</a>.</p>
 *
 *          <p>If the function's package type is <code>Image</code>, you must specify the code package in <code>ImageUri</code> as
 *       the URI of a
 *       <a href="https://docs.aws.amazon.com/lambda/latest/dg/lambda-images.html">container image</a>
 *       in the Amazon ECR registry.
 *        </p>
 *
 *          <p>If the function's package type is <code>Zip</code>, you must specify the deployment
 *       package as a <a href="https://docs.aws.amazon.com/lambda/latest/dg/gettingstarted-package.html#gettingstarted-package-zip">.zip file
 *         archive</a>. Enter the Amazon S3 bucket and key of the code .zip file location.
 *       You can also provide the function code inline using the <code>ZipFile</code> field. </p>
 *          <p>The code in the deployment package must be compatible with the target instruction set
 *       architecture of the function (<code>x86-64</code> or <code>arm64</code>). </p>
 *
 *          <p>The function's code is locked when you publish a version. You can't modify the code of a published version,
 *       only the unpublished version.</p>
 *          <note>
 *             <p>For a function defined as a container image, Lambda resolves the image tag to an image digest. In Amazon ECR, if
 *       you update the image tag to a new image, Lambda does not automatically update the function.</p>
 *          </note>
 * @example
 * Use a bare-bones client and the command you need to make an API call.
 * ```javascript
 * import { LambdaClient, UpdateFunctionCodeCommand } from "@aws-sdk/client-lambda"; // ES Modules import
 * // const { LambdaClient, UpdateFunctionCodeCommand } = require("@aws-sdk/client-lambda"); // CommonJS import
 * const client = new LambdaClient(config);
 * const command = new UpdateFunctionCodeCommand(input);
 * const response = await client.send(command);
 * ```
 *
 * @see {@link UpdateFunctionCodeCommandInput} for command's `input` shape.
 * @see {@link UpdateFunctionCodeCommandOutput} for command's `response` shape.
 * @see {@link LambdaClientResolvedConfig | config} for LambdaClient's `config` shape.
