/**
 * @dev The `Vault` is Balancer V2's core contract. A single instance of it exists for the entire network, and it is the
 * entity used to interact with Pools by Liquidity Providers who join and exit them, Traders who swap, and Asset
 * Managers who withdraw and deposit tokens.
 *
 * The `Vault`'s source code is split among a number of sub-contracts, with the goal of improving readability and making
 * understanding the system easier. Most sub-contracts have been marked as `abstract` to explicitly indicate that only
 * the full `Vault` is meant to be deployed.
 *
 * Roughly speaking, these are the contents of each sub-contract:
 *
 *  - `AssetManagers`: Pool token Asset Manager registry, and Asset Manager interactions.
 *  - `Fees`: set and compute protocol fees.
 *  - `FlashLoans`: flash loan transfers and fees.
 *  - `PoolBalances`: Pool joins and exits.
 *  - `PoolRegistry`: Pool registration, ID management, and basic queries.
 *  - `PoolTokens`: Pool token registration and registration, and balance queries.
 *  - `Swaps`: Pool swaps.
 *  - `UserBalance`: manage user balances (Internal Balance operations and external balance transfers)
 *  - `VaultAuthorization`: access control, relayers and signature validation.
 *
 * Additionally, the different Pool specializations are handled by the `GeneralPoolsBalance`,
 * `MinimalSwapInfoPoolsBalance` and `TwoTokenPoolsBalance` sub-contracts, which in turn make use of the
 * `BalanceAllocation` library.
 *
 * The most important goal of the `Vault` is to make token swaps use as little gas as possible. This is reflected in a
 * multitude of design decisions, from minor things like the format used to store Pool IDs, to major features such as
 * the different Pool specialization settings.
 *
 * Finally, the large number of tasks carried out by the Vault means its bytecode is very large, close to exceeding
 * the contract size limit imposed by EIP 170 (https://eips.ethereum.org/EIPS/eip-170). Manual tuning of the source code
 * was required to improve code generation and bring the bytecode size below this limit. This includes extensive
 * utilization of `internal` functions (particularly inside modifiers), usage of named return arguments, dedicated
 * storage access methods, dynamic revert reason generation, and usage of inline assembly, to name a few.

    // Swaps
    //
    // Users can swap tokens with Pools by calling the `swap` and `batchSwap` functions. To do this,
    // they need not trust Pool contracts in any way: all security checks are made by the Vault. They must however be
    // aware of the Pools' pricing algorithms in order to estimate the prices Pools will quote.
    //
    // The `swap` function executes a single swap, while `batchSwap` can perform multiple swaps in sequence.
    // In each individual swap, tokens of one kind are sent from the sender to the Pool (this is the 'token in'),
    // and tokens of another kind are sent from the Pool to the recipient in exchange (this is the 'token out').
    // More complex swaps, such as one token in to multiple tokens out can be achieved by batching together
    // individual swaps.
    //
    // There are two swap kinds:
    //  - 'given in' swaps, where the amount of tokens in (sent to the Pool) is known, and the Pool determines (via the
    // `onSwap` hook) the amount of tokens out (to send to the recipient).
    //  - 'given out' swaps, where the amount of tokens out (received from the Pool) is known, and the Pool determines
    // (via the `onSwap` hook) the amount of tokens in (to receive from the sender).
    //
    // Additionally, it is possible to chain swaps using a placeholder input amount, which the Vault replaces with
    // the calculated output of the previous swap. If the previous swap was 'given in', this will be the calculated
    // tokenOut amount. If the previous swap was 'given out', it will use the calculated tokenIn amount. These extended
    // swaps are known as 'multihop' swaps, since they 'hop' through a number of intermediate tokens before arriving at
    // the final intended token.
    //
    // In all cases, tokens are only transferred in and out of the Vault (or withdrawn from and deposited into Internal
    // Balance) after all individual swaps have been completed, and the net token balance change computed. This makes
    // certain swap patterns, such as multihops, or swaps that interact with the same token pair in multiple Pools, cost
    // much less gas than they would otherwise.
    //
    // It also means that under certain conditions it is possible to perform arbitrage by swapping with multiple
    // Pools in a way that results in net token movement out of the Vault (profit), with no tokens being sent in (only
    // updating the Pool's internal accounting).
    //
    // To protect users from front-running or the market changing rapidly, they supply a list of 'limits' for each token
    // involved in the swap, where either the maximum number of tokens to send (by passing a positive value) or the
    // minimum amount of tokens to receive (by passing a negative value) is specified.
    //
    // Additionally, a 'deadline' timestamp can also be provided, forcing the swap to fail if it occurs after
    // this point in time (e.g. if the transaction failed to be included in a block promptly).
    //
    // If interacting with Pools that hold WETH, it is possible to both send and receive ETH directly: the Vault will do
    // the wrapping and unwrapping. To enable this mechanism, the IAsset sentinel value (the zero address) must be
    // passed in the `assets` array instead of the WETH address. Note that it is possible to combine ETH and WETH in the
    // same swap. Any excess ETH will be sent back to the caller (not the sender, which is relevant for relayers).
    //
    // Finally, Internal Balance can be used when either sending or receiving tokens.

 * @dev https://eips.ethereum.org/EIPS/eip-712[EIP 712] is a standard for hashing and signing of typed structured data.
 *
 * The encoding specified in the EIP is very generic, and such a generic implementation in Solidity is not feasible,
 * thus this contract does not implement the encoding itself. Protocols need to implement the type-specific encoding
 * they need in their contracts using a combination of `abi.encode` and `keccak256`.
 *
 * This contract implements the EIP 712 domain separator ({_domainSeparatorV4}) that is used as part of the encoding
 * scheme, and the final step of the encoding to obtain the message digest that is then signed via ECDSA
 * ({_hashTypedDataV4}).
 *
 * The implementation of the domain separator was designed to be as efficient as possible while still properly updating
 * the chain id to protect against replay attacks on an eventual fork of the chain.
 *
 * NOTE: This contract implements the version of the encoding known as "v4", as implemented by the JSON RPC method
 * https://docs.metamask.io/guide/signing-data.html[`eth_signTypedDataV4` in MetaMask].
 *
 * _Available since v3.4._

// This library is used to create a data structure that represents a token's balance for a Pool. 'cash' is how many
// tokens the Pool has sitting inside of the Vault. 'managed' is how many tokens were withdrawn from the Vault by the
// Pool's Asset Manager. 'total' is the sum of these two, and represents the Pool's total token balance, including
// tokens that are *not* inside of the Vault.
//
// 'cash' is updated whenever tokens enter and exit the Vault, while 'managed' is only updated if the reason tokens are
// moving is due to an Asset Manager action. This is reflected in the different methods available: 'increaseCash'
// and 'decreaseCash' for swaps and add/remove liquidity events, and 'cashToManaged' and 'managedToCash' for events
// transferring funds to and from the Asset Manager.
//
// The Vault disallows the Pool's 'cash' from becoming negative. In other words, it can never use any tokens that are
// not inside the Vault.
//
// One of the goals of this library is to store the entire token balance in a single storage slot, which is why we use
// 112 bit unsigned integers for 'cash' and 'managed'. For consistency, we also disallow any combination of 'cash' and
// 'managed' that yields a 'total' that doesn't fit in 112 bits.
//
// The remaining 32 bits of the slot are used to store the most recent block when the total balance changed. This
// can be used to implement price oracles that are resilient to 'sandwich' attacks.
//
// We could use a Solidity struct to pack these three values together in a single storage slot, but unfortunately
// Solidity only allows for structs to live in either storage, calldata or memory. Because a memory struct still takes
// up a slot in the stack (to store its memory location), and because the entire balance fits in a single stack slot
// (two 112 bit values plus the 32 bit block), using memory is strictly less gas performant. Therefore, we do manual

    // These are similar to the Minimal Swap Info Pool case (because the Pool only has two tokens, and therefore there
    // are only two balances to read), but there's a key difference in how data is stored. Keeping a set makes little
    // sense, as it will only ever hold two tokens, so we can just store those two directly.
    //
    // The gas savings associated with using these Pools come from how token balances are stored: cash amounts for token
    // A and token B are packed together, as are managed amounts. Because only cash changes in a swap, there's no need
    // to write to this second storage slot. A single last change block number for both tokens is stored with the packed
    // cash fields.

    // We could just keep a mapping from Pool ID to TwoTokenSharedBalances, but there's an issue: we wouldn't know to
    // which tokens those balances correspond. This would mean having to also check which are registered with the Pool.
    //
    // What we do instead to save those storage reads is keep a nested mapping from the token pair hash to the balances
    // struct. The Pool only has two tokens, so only a single entry of this mapping is set (the one that corresponds to
    // that pair's hash).
    //
    // This has the trade-off of making Vault code that interacts with these Pools cumbersome: both balances must be
    // accessed at the same time by using both token addresses, and some logic is needed to determine how the pair hash
    // is computed. We do this by sorting the tokens, calling the token with the lowest numerical address value token A,
    // and the other one token B. In functions where the token arguments could be either A or B, we use X and Y instead.
    //
    // If users query a token pair containing an unregistered token, the Pool will generate a hash for a mapping entry
    // that was not set, and return zero balances. Non-zero balances are only possible if both tokens in the pair
    // are registered with the Pool, which means we don't have to check the TwoTokenPoolTokens struct, and can save
