/**
 * @public
 * <p>Deletes the specified NAT gateway. Deleting a public NAT gateway disassociates its Elastic IP address,
 *           but does not release the address from your account. Deleting a NAT gateway does not delete any NAT gateway
 *           routes in your route tables.</p>
 * @example
 * Use a bare-bones client and the command you need to make an API call.
 * ```javascript
 * import { EC2Client, DeleteNatGatewayCommand } from "@aws-sdk/client-ec2"; // ES Modules import
 * // const { EC2Client, DeleteNatGatewayCommand } = require("@aws-sdk/client-ec2"); // CommonJS import
 * const client = new EC2Client(config);
 * const input = { // DeleteNatGatewayRequest
 *   DryRun: true || false,
 *   NatGatewayId: "STRING_VALUE", // required
 * };
 * const command = new DeleteNatGatewayCommand(input);
 * const response = await client.send(command);
 * ```
 *
 * @param DeleteNatGatewayCommandInput - {@link DeleteNatGatewayCommandInput}
 * @returns {@link DeleteNatGatewayCommandOutput}
 * @see {@link DeleteNatGatewayCommandInput} for command's `input` shape.
 * @see {@link DeleteNatGatewayCommandOutput} for command's `response` shape.
 * @see {@link EC2ClientResolvedConfig | config} for EC2Client's `config` shape.
 *
 *
 * @example To delete a NAT gateway
 * ```javascript
 * // This example deletes the specified NAT gateway.
 * const input = {
 *   "NatGatewayId": "nat-04ae55e711cec5680"
 * };
 * const command = new DeleteNatGatewayCommand(input);
 * const response = await client.send(command);
 * /* response ==
 * {
 *   "NatGatewayId": "nat-04ae55e711cec5680"
 * }
 * *\/
 * // example id: ec2-delete-nat-gateway-1
