Struct DnsServer 

pub struct DnsServer { /* private fields */ }

Minimal UDP DNS server that answers A queries with fake IPs from a DnsMap.

Runs in a dedicated blocking thread (DNS is inherently synchronous and low-throughput enough that this is optimal).

Implementations

impl DnsServer

pub fn bind(addr: SocketAddr, map: DnsMap) -> Result<Self>

Bind to addr and create a server backed by map.

pub fn local_addr(&self) -> SocketAddr

Return the local address the server is listening on.

pub fn run(self)

Run the server loop (blocks the calling thread indefinitely).

pub fn handle_query(&self, packet: &[u8]) -> Option<Vec<u8>>

Parse a raw DNS query packet and return a DNS response allocating a fake IP from the map, or None if the packet is not a valid A query.
