# ZoneParser: A zonefile parser with good performance
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.
## Usage
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 std::fs::File;
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`.
## Bugs
- Escaped characters and octal number representations in the zonefile are
not well handled.
## Missing features
- Error handling is rather crude. Parse errors cause panic.
- 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.
## Contributing
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.
