             * 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.
