Functions

func CanonicalOperator

func CanonicalOperator(op string) string

CanonicalOperator normalizes alias operators to canonical names.

func ParseNumeric

func ParseNumeric(raw string) (any, error)

ParseNumeric parses a numeric literal into int64 or float64.

func ParseRFC3339OrUnixMs

func ParseRFC3339OrUnixMs(raw string) (time.Time, error)

ParseRFC3339OrUnixMs parses ISO8601 datetime string or unix milliseconds.

Types

type OperatorValue

type OperatorValue struct {
	Operator string
	Value    string
}

OperatorValue contains the parsed operator + value pair from an expression like "op:value".

func ParseOperatorValueEqualsOnEmptyOperator

func ParseOperatorValueEqualsOnEmptyOperator(raw string) OperatorValue

ParseOperatorValueEqualsOnEmptyOperator parses "op:value" while treating empty op as equals. This preserves legacy behavior used by query normalizer.

func ParseOperatorValueLenient

func ParseOperatorValueLenient(raw string) OperatorValue

ParseOperatorValueLenient parses "op:value"; malformed pairs fallback to equals(raw).

func ParseOperatorValueStrict

func ParseOperatorValueStrict(raw string) (OperatorValue, error)

ParseOperatorValueStrict parses "op:value"; malformed pairs return an error.

type SQLOperatorResult

type SQLOperatorResult struct {
	SQLOperator string
	Value       string
}

SQLOperatorResult maps an operator token to SQL syntax and the normalized value.

func ToSQLOperator

func ToSQLOperator(op, value string) (SQLOperatorResult, error)

ToSQLOperator converts a logical operator to SQL syntax. For LIKE operators, it also applies wildcard normalization to value.
