my $level = $err->level
    Return the raw error level represented by this error. One of the ERROR LEVEL CONSTANTS

my $code = $err->code
    Return the raw error code represented by this error. One of the ERROR CODE CONSTANTS

my $from = $err->domain
    Return the error domain raising this error. One of the ERROR DOMAIN CONSTANTS
