The ZoneParser is a DNS zonefile parser. It has been designed to have a good performance with regards to cpu and memory consumption. It works well with large zonefiles. The code is in an early stage of development and still has a somewhat limited functionality.
The parser is constructed with a file as input. It then works as an iterator yielding the resource records of the zone. An example:
use zoneparser::ZoneParser;
fn main() {
let file = File::open("my-zone.no").unwrap();
let p = ZoneParser::new(&file);
for rr in p {
println!("{}", rr);
}
}
For further examples, see the included command line tools zonecount
and zonediff.
- Escaped characters and octal number representations in the zonefile are not well handled.
- Error handling is rather crude. Parse errors cause panic. Quoted strings are somewhat poorly handled, esp. with escaped content.
- Only the common record fields are parsed. Content specific to the record types are returned as anonymous data fields. A later version might support parsing the data content as a secondary function call.
- Relative names are not converted to absolute ones.
The limited functionality very much reflects the needs I had when I wrote the library. If you find it useful, and miss some functionality, please let me know. It might motivate me to further development. Bug reports are always welcome.
