/**
 * @dev Interface of the ERC20 Permit extension allowing approvals to be made via signatures, as defined in
 * https://eips.ethereum.org/EIPS/eip-2612[EIP-2612].
 *
 * Adds the {permit} method, which can be used to change an account's ERC20 allowance (see {IERC20-allowance}) by
 * presenting a message signed by the account. By not relying on {IERC20-approve}, the token holder account doesn't
 * need to send a transaction, and thus is not required to hold Ether at all.
 *
 * ==== Security Considerations
 *
 * There are two important considerations concerning the use of `permit`. The first is that a valid permit signature
 * expresses an allowance, and it should not be assumed to convey additional meaning. In particular, it should not be
 * considered as an intention to spend the allowance in any specific way. The second is that because permits have
 * built-in replay protection and can be submitted by anyone, they can be frontrun. A protocol that uses permits should
 * take this into consideration and allow a `permit` call to fail. Combining these two aspects, a pattern that may be
 * generally recommended is:
 *
 * ```solidity
 * function doThingWithPermit(..., uint256 value, uint256 deadline, uint8 v, bytes32 r, bytes32 s) public {
 *     try token.permit(msg.sender, address(this), value, deadline, v, r, s) {} catch {}
 *     doThing(..., value);
 * }
 *
 * function doThing(..., uint256 value) public {
 *     token.safeTransferFrom(msg.sender, address(this), value);
 *     ...
 * }
 * ```
 *
 * Observe that: 1) `msg.sender` is used as the owner, leaving no ambiguity as to the signer intent, and 2) the use of
 * `try/catch` allows the permit to fail and makes the code tolerant to frontrunning. (See also
 * {SafeERC20-safeTransferFrom}).
 *
 * Additionally, note that smart contract wallets (such as Argent or Safe) are not able to produce permit signatures, so
 * contracts should have entry points that don't rely on permit.

import { BusPassenger, BusCodec } from "./BusCodec.sol";

/* Bus Parameters
    There is three relevant bus parameters regarding the number of passengers than can queue up for it 
    and later sit on it to be driven:

    queueCapacity
    maxNumPassengers
    plannerPassengers

    In simple terms, up to queueCapacity passengers can queue up at once, up to maxNumPassengers can be driven per bus
    at once, and plannerPassengers passengers will be driven under steady state conditions. 
    
    When and how to set these parameters is explained next:

    queueCapacity
    Queue capacity is an on-chain parameter set at deployment time (it is part of the constructor). It limits the amount
    of passengers that can queue up for the bus at once. It also sets the size of the circular buffer used to represent
    the queue. The capacity impacts the cost of initialization since each capacity slot should be initialized, so it is
    a number that we want to bound. At the same time, the size of the circular buffer defines the bus behaviour under
    re-orgs: Because a re-org will re-order txs, that changes the hashChain, which will cause the `drive` txs to revert
    as they will contain the wrong hashes. Reverting the drives means that in the now-canonical fork there is no
    available room in the queue for all the passengers that queued up in the abandoned fork. This will cause all those
    txs to revert as well, leading to a bad UX. If the circular buffer is made larger, then the passengers txs can
    still be re-arranged despite all the `drive` txs reverting. This parameter should be set by estimating the inflow
    of txs for each chain and multiplying that by the p99 finality window (confirmation time) or another such indicator
    to minimize the chances that passengers `ride` tx revert under re-orgs. Naturally the queue constrains the
    `maxNumPassengers`.

    maxNumPassengers
    The max number of passengers to drive is an on-chain parameter that limits how many passengers can be driven at
    once. It is set through the `setMaxNumPassengers` function at wire/configure time but can be later
    modified. Its purpose is to ensure that all LZ messages are deliverable. Since LZ has a limit on the destination on
    the message size, we need to ensure on the source that we do not go above that limit.

    plannerPassengers
    The number of passengers that the Planner will actually attempt to drive. This is an off-chain parameter that tries
    to balance cost (by driving as many passengers as possible at once) with speed (by driving as often as possible).
    It is dynamically set on the off-chain side and the only significance on the contract side is that it corresponds
    to the typical value the contract will see on calls to `ride`.

    The way each parameter limits the next one means queueCapacity > maxNumPassengers > plannerPassengers.
