Types

type Error

type Error struct {
	// Message contains the readable message of error
	Message string
	ErrType int
}

Error represents parser's parsing error

func InitError

func InitError(msg string, errType int) *Error

InitError is a helper function for easily initializing error object

NewArgumentError is a helper function the helps initializing argument errors

func NewTypeParsingError

func NewTypeParsingError(tokenLiteral, targetType string, line int) *Error

NewTypeParsingError is a helper function the helps initializing type parsing errors
