path

IP based connection identification and tracing

This crate is highly inspired by the netfilter project, which provides connection tracking for TCP/IP based protocols. The timeout of a connection (per default 10 minutes) is handled completely internally by using the time crate.

Example usage

```rust use path::{Path, Identifier}; use std::net::{IpAddr, Ipv4Addr};

// Create a new Path for tracking u8 values as custom data let mut path :Path = Path::new();

// Build up a new identifier from IP Addresses, their ports, and a key (in this case the IP Protocol) let identifier = Identifier::new(IpAddr::V4(Ipv4Addr::new(10, 0, 0, 1)), 1234, IpAddr::V4(Ipv4Addr::new(10, 0, 0, 2)), 443, 6);

// Do the actual work let data = path.track(&identifier).unwrap();

// Now it is possible to set/get the custom data asserteq!(data.custom, None); asserteq!(data.packet_counter, 1); ```
