/**
 * <p>Returns the data in a block in an Amazon Elastic Block Store snapshot.</p>
 *          <note>
 *             <p>You should always retry requests that receive server (<code>5xx</code>)
 *     error responses, and <code>ThrottlingException</code> and <code>RequestThrottledException</code>
 *     client error responses. For more information see <a href="https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/error-retries.html">Error retries</a> in the

 *          </note>
 * @example
 * Use a bare-bones client and the command you need to make an API call.
 * ```javascript
 * import { EBSClient, GetSnapshotBlockCommand } from "@aws-sdk/client-ebs"; // ES Modules import
 * // const { EBSClient, GetSnapshotBlockCommand } = require("@aws-sdk/client-ebs"); // CommonJS import
 * // import type { EBSClientConfig } from "@aws-sdk/client-ebs";
 * const config = {}; // type is EBSClientConfig
 * const client = new EBSClient(config);
 * const input = { // GetSnapshotBlockRequest
 *   SnapshotId: "STRING_VALUE", // required
 *   BlockIndex: Number("int"), // required
 *   BlockToken: "STRING_VALUE", // required
 * };
 * const command = new GetSnapshotBlockCommand(input);
 * const response = await client.send(command);
 * // consume or destroy the stream to free the socket.
 * const bytes = await response.BlockData.transformToByteArray();
 * // const str = await response.BlockData.transformToString();
 * // response.BlockData.destroy(); // only applicable to Node.js Readable streams.
 *
 * // { // GetSnapshotBlockResponse
 * //   DataLength: Number("int"),
 * //   BlockData: "<SdkStream>", // see \@smithy/types -> StreamingBlobPayloadOutputTypes
 * //   Checksum: "STRING_VALUE",
 * //   ChecksumAlgorithm: "SHA256",
 * // };
