Expand description

DNS client for querying overlay DNS servers

Implementations§

Source §

impl DnsClient

Source

pub fn new(server_addr: SocketAddr) -> Self

Create a new DNS client

Source

pub fn query_a(&self, hostname: &str) -> Result<Option<Ipv4Addr>, DnsError>

Query for an A record

§Errors

Returns a DnsError if the query fails or the hostname is invalid.

Source

pub fn query_aaaa(&self, hostname: &str) -> Result<Option<Ipv6Addr>, DnsError>

Query for an AAAA record (IPv6)

§Errors

Returns a DnsError if the query fails or the hostname is invalid.

Source

pub fn query_addr(&self, hostname: &str) -> Result<Option<IpAddr>, DnsError>

Query for any address record (A or AAAA), returning the first match

Tries A first, then AAAA. Returns the first successful result.

§Errors

Returns a DnsError if both queries fail or the hostname is invalid.
