/**
* @dev Contract module that allows children to implement role-based access
* control mechanisms. This is a lightweight version that doesn't allow enumerating role
* members except through off-chain means by accessing the contract event logs. Some
* applications may benefit from on-chain enumerability, for those cases see
* {AccessControlEnumerable}.
*
* Roles are referred to by their `bytes32` identifier. These should be exposed
* in the external API and be unique. The best way to achieve this is by
* using `public constant` hash digests:
*
* ```solidity
* bytes32 public constant MY_ROLE = keccak256("MY_ROLE");
* ```
*
* Roles can be used to represent a set of permissions. To restrict access to a
* function call, use {hasRole}:
*
* ```solidity
* function foo() public {
* require(hasRole(MY_ROLE, msg.sender));
* ...
* }
* ```
*
* Roles can be granted and revoked dynamically via the {grantRole} and
* {revokeRole} functions. Each role has an associated admin role, and only
* accounts that have a role's admin role can call {grantRole} and {revokeRole}.
*
* By default, the admin role for all roles is `DEFAULT_ADMIN_ROLE`, which means
* that only accounts with this role will be able to grant or revoke other
* roles. More complex role relationships can be created by using
* {_setRoleAdmin}.
*
* WARNING: The `DEFAULT_ADMIN_ROLE` is also its own admin: it has permission to
* grant and revoke this role. Extra precautions should be taken to secure
* accounts that have been granted it. We recommend using {AccessControlDefaultAdminRules}
* to enforce additional security measures for this role.

/**
* @dev Implementation of the ERC-4626 "Tokenized Vault Standard" as defined in
* https://eips.ethereum.org/EIPS/eip-4626[ERC-4626].
*
* This extension allows the minting and burning of "shares" (represented using the ERC-20 inheritance) in exchange for
* underlying "assets" through standardized {deposit}, {mint}, {redeem} and {burn} workflows. This contract extends
* the ERC-20 standard. Any additional extensions included along it would affect the "shares" token represented by this
* contract and not the "assets" token which is an independent contract.
*
* [CAUTION]
* ====
* In empty (or nearly empty) ERC-4626 vaults, deposits are at high risk of being stolen through frontrunning
* with a "donation" to the vault that inflates the price of a share. This is variously known as a donation or inflation
* attack and is essentially a problem of slippage. Vault deployers can protect against this attack by making an initial
* deposit of a non-trivial amount of the asset, such that price manipulation becomes infeasible. Withdrawals may
* similarly be affected by slippage. Users can protect against this attack as well as unexpected slippage in general by
* verifying the amount received is as expected, using a wrapper that performs these checks such as
* https://github.com/fei-protocol/ERC4626#erc4626router-and-base[ERC4626Router].
*
* Since v4.9, this implementation introduces configurable virtual assets and shares to help developers mitigate that risk.
* The `_decimalsOffset()` corresponds to an offset in the decimal representation between the underlying asset's decimals
* and the vault decimals. This offset also determines the rate of virtual shares to virtual assets in the vault, which
* itself determines the initial exchange rate. While not fully preventing the attack, analysis shows that the default
* offset (0) makes it non-profitable even if an attacker is able to capture value from multiple user deposits, as a result
* of the value being captured by the virtual shares (out of the attacker's donation) matching the attacker's expected gains.
* With a larger offset, the attack becomes orders of magnitude more expensive than it is profitable. More details about the
* underlying math can be found xref:ROOT:erc4626.adoc#inflation-attack[here].
*
* The drawback of this approach is that the virtual shares do capture (a very small) part of the value being accrued
* to the vault. Also, if the vault experiences losses, the users try to exit the vault, the virtual shares and assets
* will cause the first user to exit to experience reduced losses in detriment to the last users that will experience
* bigger losses. Developers willing to revert back to the pre-v4.9 behavior just need to override the
* `_convertToShares` and `_convertToAssets` functions.
*
* To learn more, check out our xref:ROOT:erc4626.adoc[ERC-4626 guide].
* ====
*
* [NOTE]
* ====
* When overriding this contract, some elements must be considered:
*
* * When overriding the behavior of the deposit or withdraw mechanisms, it is recommended to override the internal
* functions. Overriding {_deposit} automatically affects both {deposit} and {mint}. Similarly, overriding {_withdraw}
* automatically affects both {withdraw} and {redeem}. Overall it is not recommended to override the public facing
* functions since that could lead to inconsistent behaviors between the {deposit} and {mint} or between {withdraw} and
* {redeem}, which is documented to have lead to loss of funds.
*
* * Overrides to the deposit or withdraw mechanism must be reflected in the preview functions as well.
*
* * {maxWithdraw} depends on {maxRedeem}. Therefore, overriding {maxRedeem} only is enough. On the other hand,
* overriding {maxWithdraw} only would have no effect on {maxRedeem}, and could create an inconsistency between the two
* functions.
*
* * If {previewRedeem} is overridden to revert, {maxWithdraw} must be overridden as necessary to ensure it
* always return successfully.
