Struct Scanner 

pub struct Scanner { /* private fields */ }

Main network scanner struct.

The scanner coordinates network discovery and monitoring operations including ARP scanning, packet capture, and host detection.

Implementations

impl Scanner

pub fn new( scanner_outputs: Sender<Event>, interface_name: String, backend_type: BackendType, ) -> AppResult<Self>

Creates a new Scanner with the specified configuration.

Arguments

• scanner_outputs - Channel for sending scanner events
• interface_name - Name of the network interface to use
• backend_type - Type of backend to use (pnet or eBPF)

Returns

A new Scanner instance, or an error if initialization fails

pub fn send_arp_packets(&self)

Send ARP packets to discover hosts on the network.

This triggers an ARP scan of the network range(s) configured on the selected interface.

pub fn gateway_ip(&self) -> Option<Ipv4Addr>

Get the detected default gateway IP address.

Returns None if no gateway was detected or if detection failed.

pub fn local_ips(&self) -> &HashSet<Ipv4Addr>

Get the set of detected local IP addresses.

Returns the set of IPs on the local interfaces that were detected during startup.

pub fn remove_discovered_hosts(&self, ips: &[Ipv4Addr])

Remove hosts from the discovered set, allowing them to be re-discovered.

This should be called when hosts are cleared/deleted from the UI.

Arguments

• ips - Slice of IP addresses to remove from the discovered set

fn drop(&mut self)

Executes the destructor for this type.
