 * <p>Sets the maximum number of simultaneous executions for a function, and reserves capacity for that concurrency
 *       level.</p>
 *          <p>Concurrency settings apply to the function as a whole, including all published versions and the unpublished
 *       version. Reserving concurrency both ensures that your function has capacity to process the specified number of
 *       events simultaneously, and prevents it from scaling beyond that level. Use <a>GetFunction</a> to see
 *       the current setting for a function.</p>
 *          <p>Use <a>GetAccountSettings</a> to see your Regional concurrency limit. You can reserve concurrency
 *       for as many functions as you like, as long as you leave at least 100 simultaneous executions unreserved for
 *       functions that aren't configured with a per-function limit. For more information, see <a href="https://docs.aws.amazon.com/lambda/latest/dg/invocation-scaling.html">Lambda function scaling</a>.</p>
 * @example
 * Use a bare-bones client and the command you need to make an API call.
 * ```javascript
 * import { LambdaClient, PutFunctionConcurrencyCommand } from "@aws-sdk/client-lambda"; // ES Modules import
 * // const { LambdaClient, PutFunctionConcurrencyCommand } = require("@aws-sdk/client-lambda"); // CommonJS import
 * const client = new LambdaClient(config);
 * const input = { // PutFunctionConcurrencyRequest
 *   FunctionName: "STRING_VALUE", // required
 *   ReservedConcurrentExecutions: Number("int"), // required
 * };
 * const command = new PutFunctionConcurrencyCommand(input);
 * const response = await client.send(command);
 * // { // Concurrency
 * //   ReservedConcurrentExecutions: Number("int"),
 * // };
 *
 * ```
 *
 * @param PutFunctionConcurrencyCommandInput - {@link PutFunctionConcurrencyCommandInput}
 * @returns {@link PutFunctionConcurrencyCommandOutput}
 * @see {@link PutFunctionConcurrencyCommandInput} for command's `input` shape.
 * @see {@link PutFunctionConcurrencyCommandOutput} for command's `response` shape.
 * @see {@link LambdaClientResolvedConfig | config} for LambdaClient's `config` shape.
 *
 * @throws {@link InvalidParameterValueException} (client fault)
 *  <p>One of the parameters in the request is not valid.</p>
 *
 * @throws {@link ResourceConflictException} (client fault)

 *
 * @throws {@link ResourceNotFoundException} (client fault)
 *  <p>The resource specified in the request does not exist.</p>
 *
 * @throws {@link ServiceException} (server fault)
