Struct Resolver 

pub struct Resolver { /* private fields */ }

Looks up the DNS sources.

Build one and keep it. It holds the resolver configuration and a cache of answers.

use abuse_contact::Resolver;

let resolver = Resolver::new()?;

// AFRINIC publishes no abuse contact in RDAP. Abusix has one.
for contact in resolver.abusix("196.216.2.1".parse().unwrap()).await? {
    println!("{} ({:?})", contact.email, contact.scope);
}

Implementations

impl Resolver

pub fn new() -> Result<Self, Error>

Returns a resolver that uses the resolver configuration of the system.

Errors

Returns Error::Dns when the system configuration cannot be read.

pub fn with_nameservers(nameservers: &[SocketAddr]) -> Result<Self, Error>

Returns a resolver that asks these nameservers, over UDP and TCP.

Errors

Returns Error::Dns when the resolver cannot be built.

pub async fn abusix(&self, ip: IpAddr) -> Result<Vec<Contact>, Error>

Returns the contacts Abusix gives for the network that holds an address.

Abusix answers for AFRINIC space, where RDAP publishes no abuse entity.

Errors

Returns Error::NotPublic for a private or reserved address, and Error::Dns when the lookup does not finish.

pub async fn abuse_net( &self, domain: &DomainName, ) -> Result<Vec<Contact>, Error>

Returns the contacts abuse.net gives for a domain.

Errors

Returns Error::Dns when the lookup does not finish.

pub async fn rfc2142( &self, domain: &DomainName, ) -> Result<Option<Contact>, Error>

Returns abuse@ at the domain, when the domain takes mail.

RFC 2142 requires the mailbox, and many domains do not have it, so the address is a guess. A domain that takes no mail cannot have it at all, and gives None: a name that does not exist, a null MX, or no MX and no address.

Errors

Returns Error::Dns when a lookup does not finish.
