The {initializer} modifier provided by this contract will have this effect.\n *\n * The initialization functions use a version number. Once a version number is used, it is consumed and cannot be\n * reused. This mechanism prevents re-execution of each \"step\" but allows the creation of new initialization steps in\n * case an upgrade adds a module that needs to be initialized.\n *\n * For example:\n *\n * [.hljs-theme-light.nopadding]\n * ```solidity\n * contract MyToken is ERC20Upgradeable {\n * function initialize() initializer public {\n * __ERC20_init(\"MyToken\", \"MTK\");\n * }\n * }\n *\n * contract MyTokenV2 is MyToken, ERC20PermitUpgradeable {\n * function initializeV2() reinitializer(2) public {\n * __ERC20Permit_init(\"MyToken\");\n * }\n * }\n * ```\n *\n * TIP: To avoid leaving the proxy in an uninitialized state, the initializer function should be called as early as\n * possible by providing the encoded function call as the `_data` argument to {ERC1967Proxy-constructor}.\n *\n * CAUTION: When used with inheritance, manual care must be taken to not invoke a parent initializer twice, or to ensure\n * that all initializers are idempotent. This is not verified automatically as constructors are by Solidity.\n *\n * [CAUTION]\n * ====\n * Avoid leaving a contract uninitialized.\n *\n * An uninitialized contract can be taken over by an attacker. This applies to both a proxy and its implementation\n * contract, which may impact the proxy.

This contract provides a basic framework for\n * rate limiting how often a function can be executed. It is designed to be inherited by other contracts requiring rate\n * limiting capabilities to protect resources or services from excessive use.\n * @dev The ordering of transactions within a given block (timestamp) affects the consumed capacity.\n * @dev Carefully consider the minimum window duration for the given blockchain. For example, on Ethereum, the minimum\n * window duration should be at least 12 seconds. If a window less than 12 seconds is configured, then the rate limit\n * will effectively reset with each block, rendering rate limiting ineffective.\n * @dev Carefully consider the proportion of the limit to the window. If the limit is much smaller than the window, the\n * decay function is lossy. Consider using a limit that is greater than or equal to the window to avoid this. This is\n * especially important for blockchains with short average block times.\n *\n * Example 1: Max rate limit reached at beginning of window. As time continues the amount of in flights comes down.\n *\n * Rate Limit Config:\n * limit: 100 units\n * window: 60 seconds\n *\n * Amount in Flight (units) vs. Time Graph (seconds)\n *\n * 100 | * - (Max limit reached at beginning of window)\n * | *\n * | *\n * | *\n * 50 | * (After 30 seconds only 50 units in flight)\n * | *\n * | *\n * | *\n * 0 +--|---|---|---|---|-->(After 60 seconds 0 units are in flight)\n * 0 15 30 45 60 (seconds)\n *\n * Example 2: Max rate limit reached at beginning of window. As time continues the amount of in flights comes down\n * allowing for more to be sent. At the 90 second mark, more in flights come in.\n *\n * Rate Limit Config:\n * limit: 100 units\n * window: 60 seconds\n *\n * Amount in Flight (units) vs. Time Graph (seconds)\n *\n * 100 | * - (Max limit reached at beginning of window)\n * | *\n * | *\n * | *\n * 50 | * * (50 inflight)\n * | * *\n * | * *\n * | * *\n * 0 +--|--|--|--|--|--|--|--|--|--> Time\n * 0 15 30 45 60 75 90 105 120 (seconds)\n *\n * Example 3: Max rate limit reached at beginning of window.
