## DESCRIPTION
    [Net::Twitter::Error](https://www.chedong.com/phpMan.php/perldoc/Net%3A%3ATwitter%3A%3AError/markdown) encapsulates the "[HTTP::Response](https://www.chedong.com/phpMan.php/perldoc/HTTP%3A%3AResponse/markdown)" and Twitter error HASH (if any) resulting
    from a failed API call.

## METHODS
    new Constructs a "[Net::Twitter::Error](https://www.chedong.com/phpMan.php/perldoc/Net%3A%3ATwitter%3A%3AError/markdown)" object. It accepts the following parameters:

        http_response
            An "[HTTP::Response](https://www.chedong.com/phpMan.php/perldoc/HTTP%3A%3AResponse/markdown)" object, required.

        twitter_error
            The error returned by Twitter as a HASH ref. Optional, since some API errors do not
            include a response from Twitter. They may, instead, be the result of network timeouts,
            proxy errors, or some other problem that prevents an API response.

    twitter_error
        Get or set the Twitter error HASH.

    http_response
        Get or set the "[HTTP::Response](https://www.chedong.com/phpMan.php/perldoc/HTTP%3A%3AResponse/markdown)" object.

    code
        Returns the HTTP response code.

    message
        Returns the HTTP response message.

    has_twitter_error
        Returns true if the object contains a Twitter error HASH.

    error
        Returns the "error" value from the "twitter_error" HASH ref if there is one. Otherwise, it
        returns the string "[unknown]". Includes a stack trace.

    twitter_error_text
        Returns the "error" value from the "twitter_error" HASH ref if there is one. Otherwise,
        returns an empty string

    twitter_error_code
        Returns the first numeric twitter error code from the JSON response body, if there is one.
        Otherwise, it returns 0 so the result should always be safe use in a numeric test.

        See Twitter Error Codes <<https://dev.twitter.com/docs/error-codes-responses>> for a list of
        defined error codes.

    stack_trace
        Returns a [Devel::StackTrace](https://www.chedong.com/phpMan.php/perldoc/Devel%3A%3AStackTrace/markdown) object.

### stack_frame
        Returns the $ith stack frame as a [Devel::StackTrace::Frame](https://www.chedong.com/phpMan.php/perldoc/Devel%3A%3AStackTrace%3A%3AFrame/markdown) object.
