	Operator OperatorKind
	Right    Value
}

a operator b.

func (*CompareExpr) String

type Error

type Error struct {
	// contains filtered or unexported fields
}

	Equals OperatorKind = iota
	NotEquals
	Less
	LessEquals
	Greater
	GreaterEquals
	Like
	ILike
	In //nolint:varnamelen

type ValidationError

type ValidationError struct {
	// contains filtered or unexported fields
}

func NewValidationError

func NewValidationError(format string, a ...interface{}) *ValidationError

func (*ValidationError) Error

func (e *ValidationError) Error() string

type Value

type Value interface {
	fmt.Stringer
	// contains filtered or unexported methods
}
