Required Associated Types

type Error: Into<Box<dyn Error + Sync + Send>> + Send + 'static

Error returned by the DnsResolver

Required Methods

fn txt_lookup( &self, domain: Domain, ) -> impl Future<Output = Result<Vec<Vec<u8>>, Self::Error>> + Send

Resolve the ‘TXT’ records accessible by this resolver for the given key.

fn ipv4_lookup( &self, domain: Domain, ) -> impl Future<Output = Result<Vec<Ipv4Addr>, Self::Error>> + Send

Resolve the ‘A’ records accessible by this resolver for the given Domain into Ipv4Addresses.

fn ipv6_lookup( &self, domain: Domain, ) -> impl Future<Output = Result<Vec<Ipv6Addr>, Self::Error>> + Send

Resolve the ‘AAAA’ records accessible by this resolver for the given Domain into Ipv6Addresses.

Provided Methods

fn boxed(self) -> BoxDnsResolver

Box this resolver to allow for dynamic dispatch.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
