impl Capture[src]
fn new<D: AsRef<str>>(device: D) -> Result<Capture, Error>
Creates a capture handle from the specified device, or an error from pcap.
You can provide this a Device from Devices::list_all() or an &str name of
the device such as "any" on Linux.
fn next<'a>(&'a mut self) -> Option<&'a [u8]>
Blocks until a packet is returned from the capture handle or an error occurs.
fn filter(&mut self, program: &str) -> Result<(), Error>
Adds a filter to the capture using the given BPF program string. Internally
this is compiled using pcap_compile().
