ErrRequiresRoleOption can be used to construct an error that tells the user a given role option or privilege is required.

NewChecker constructs a new CheckerForRPCHandlers.

ErrRequiresAdmin is returned when the admin role is required by an API.

CheckerForRPCHandlers describes a helper for checking privileges.

SQLPrivilegeChecker is the part of the privilege checker that can be used outside of RPC handlers, because it takes the identity as explicit argument.
