func FilterString ¶

func FilterString(rules []mss.Rule) string

FilterString returns an SQL WHERE statement that pre-filters rows for this set of rules. Only supports "equal strings" filters.

Rules for:

#foo [type='bar'][level=2] {}
#foo [type='baz'][level=2] {}

will return

"(type IN ('bar', 'baz'))"

Rules for:

#foo [level=2] {}
#foo [type='bar'][level=2] {}

will return an empty string, since any 'type' can match.
