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.",
