func MatchesRecord ¶ added in v1.13.0

func MatchesRecord(expression string, record map[string]interface{}) (bool, error)

MatchesRecord evaluates a kubectl-style JSONPath filter expression against an MMDB record. The expression is applied to a single-element slice that wraps the record, so @ refers directly to the record's fields:

{[?(@.country.iso_code=="US")]}

Returns true when the expression produces non-empty output (i.e. the filter matched), false when the output is empty (no match), and an error when the expression itself is invalid.

func ValidateExpression ¶

func ValidateExpression(expression string) error

ValidateExpression parses the expression and returns an error if it is syntactically invalid. Call this once up-front to give users a clear error before starting any expensive iteration.
