PCAP parser
PCAP and PCAPNG parsers
This crate contains several parsers for PCAP and PCAPNG files.
Compared to other similar projects, it is designed to offer a complete support of the many possible formats (legacy pcap, pcapng, little or big-endian, etc.) and features (pcanpng files with multiple sections, interfaces, and endianness) while using only safe code and without copying data (zero-copy).
The code is available on Github and is part of the Rusticata project.
Example: streaming parsers
The following code shows how to parse a file in the pcap-ng format, using a PcapNGReader streaming parser.
use *;
use PcapReaderIterator;
use ErrorKind;
use File;
use Read;
let mut file = open.unwrap;
let mut num_blocks = 0;
let mut reader = new.expect;
loop
println!;
See PcapNGReader for a complete example, including handling of linktype and accessing packet data.
For legacy pcap files, use similar code with the LegacyPcapReader streaming parser.
See pcap-tools and pcap-parse for more examples.
Example: generic streaming parsing
To create a pcap reader for input in either PCAP or PCAPNG format, use the create_reader function.
