Struct pcap_file::reader::PcapReader [−] [src]

pub struct PcapReader<T: Read> {
    pub header: PcapHeader,
    // some fields omitted
}

This struct wraps another reader and enables it to read a Pcap formated stream.

It implements the Iterator trait in order to read one packet at a time

Exemple

use std::fs::File;
use pcap_file::{PcapReader, PcapWriter};

let file_in = File::open("test.pcap").expect("Error opening file");
let pcap_reader = PcapReader::new(file_in).unwrap();

let file_out = File::create("out.pcap").expect("Error creating file");
let mut pcap_writer = PcapWriter::new(file_out).unwrap();

// Read test.pcap
for pcap in pcap_reader {

    //Write each packet of test.pcap in out.pcap
    pcap_writer.write_packet(&pcap);
}

Fields

Methods

impl<T: Read> PcapReader<T>
[src]

Create a new PcapReader from an existing reader. This function read the global pcap header of the file to verify its integrity.

The underlying reader must point to a valid pcap file/stream.

Errors

Return an error if the data stream is not in a valid pcap file format. Or if the underlying data are not readable.

Exemple

use std::fs::File;
use pcap_file::PcapReader;

let file_in = File::open("test.pcap").expect("Error opening file");
let pcap_reader = PcapReader::new(file_in).unwrap();

Consumes the PcapReader, returning the wrapped reader.

Exemple

use std::fs::File;
use pcap_file::PcapReader;

let file = File::open("test.pcap").expect("Error opening file");
let pcap_reader = PcapReader::new(file).unwrap();

let file2 = pcap_reader.into_reader();

Gets a reference to the underlying reader.

It is inadvisable to directly read from the underlying reader.

Exemple

use std::fs::File;
use pcap_file::PcapReader;

let file = File::open("test.pcap").expect("Error opening file");
let pcap_reader = PcapReader::new(file).unwrap();

let file_ref = pcap_reader.get_ref();

Gets a mutable reference to the underlying reader.

It is inadvisable to directly read from the underlying reader.

Exemple

use std::fs::File;
use pcap_file::PcapReader;

let file = File::open("test.pcap").expect("Error opening file");
let mut pcap_reader = PcapReader::new(file).unwrap();

let file_mut = pcap_reader.get_mut();
