Note that any function without this setup won't be * effectively restricted. * * The restriction rules for such functions are defined in terms of "roles" identified by an `uint64` and scoped * by target (`address`) and function selectors (`bytes4`). These roles are stored in this contract and can be * configured by admins (`ADMIN_ROLE` members) after a delay (see {getTargetAdminDelay}). * * For each target contract, admins can configure the following without any delay: * * * The target's {AccessManaged-authority} via {updateAuthority}. * * Close or open a target via {setTargetClosed} keeping the permissions intact. * * The roles that are allowed (or disallowed) to call a given function (identified by its selector) through {setTargetFunctionRole}. * * By default every address is member of the `PUBLIC_ROLE` and every target function is restricted to the `ADMIN_ROLE` until configured otherwise. * Additionally, each role has the following configuration options restricted to this manager's admins: * * * A role's admin role via {setRoleAdmin} who can grant or revoke roles. * * A role's guardian role via {setRoleGuardian} who's allowed to cancel operations. * * A delay in which a role takes effect after being granted through {setGrantDelay}. * * A delay of any target's admin action via {setTargetAdminDelay}. * * A role label for discoverability purposes with {labelRole}. * * Any account can be added and removed into any number of these roles by using the {grantRole} and {revokeRole} functions * restricted to each role's admin (see {getRoleAdmin}). * * Since all the permissions of the managed system can be modified by the admins of this instance, it is expected that * they will be highly secured (e.g., a multisig or a well-configured DAO). * * NOTE: This contract implements a form of the {IAuthority} interface, but {canCall} has additional return data so it * doesn't inherit `IAuthority`. It is however compatible with the `IAuthority` interface since the first 32 bytes of * the return data are a boolean as expected by that interface. * * NOTE: Systems that implement other access control mechanisms (for example using {Ownable}) can be paired with an * {AccessManager} by transferring permissions (ownership in the case of {Ownable}) directly to the {AccessManager}. * Users will be able to interact with these contracts through the {execute} function, following the access rules * registered in the {AccessManager}. Keep in mind that in that context, the msg.sender seen by restricted functions * will be {AccessManager} itself. * * WARNING: When granting permissions over an {Ownable} or {AccessControl} contract to an {AccessManager}, be very * mindful of the danger associated with functions such as {{Ownable-renounceOwnership}} or * {{AccessControl-renounceRole}}. */ contract AccessManagerUpgradeable is Initializable, ContextUpgradeable, MulticallUpgradeable, IAccessManager { using Time for *; // Structure that stores the details for a target contract. struct TargetConfig { mapping(bytes4 selector => uint64 roleId) allowedRoles; Time.Delay adminDelay; bool closed; } // Structure that stores the details for a role/account pair.
