Struct DefaultDnsClient 

pub struct DefaultDnsClient { /* private fields */ }

Implementation of a DnsClient that uses UDP with TCP fallback.

Supports nameserver rotation, retries, timeouts, and pooling of client connections. Names are assumed to already be fully qualified, meaning that they are not combined with a search domain.

Timeouts are handled by the client itself and so callers should not add a timeout on the resolve method. Note that timeouts are per-network operation. This means that a single call to resolve make take longer than the timeout since failed network operations are retried.

Implementations

impl DefaultDnsClient

pub fn new<U, T>( config: DnsClientConfig, udp_factory: U, tcp_factory: T, ) -> Self

where U: ClientFactory<SocketAddr, UdpConnection> + Send + Sync + 'static, T: ClientFactory<SocketAddr, TcpConnection> + Send + Sync + 'static,

Create a new DnsClient that will resolve names using UDP or TCP connections and behavior based on a resolv.conf configuration file.
