Encoder/decoder for the raw format of [PHP's dns_get_record function](https://www.php.net/manual/en/function.dns-get-record.php) based on [libdns](https://github.com/DaveRandom/LibDNS/): allows usage of the function to fetch **all kinds of DNS records**, not just the ones supported by the `DNS_` constants.
|
||
|
|
|
||
|
|
The API consists of a `NativeEncoderFactory` that creates `NativeEncoder` objects, that can encode libdns `Message` objects to a list of parameters that that must be passed to the `dns_get_record` function.
|
||
|
|
|
||
|
|
The `NativeDecoderFactory` creates `NativeDecoder` objects, that accept the results of the `dns_get_record` function and decode them back to `Message` objects.
