//! This module holds [DnsClient](crate::DnsClient) trait implementations on top of
//! [trust-dns](https://docs.rs/trust-dns-resolver/0.20.3/trust_dns_resolver/).
//!
//! 2 clients are provided, one async built on top of
//! [AsyncResolver](https://docs.rs/trust-dns-resolver/0.20.3/trust_dns_resolver/struct.AsyncResolver.html)
//! of `trust-dns` and one sync built on top of [Resolver](https://docs.rs/trust-dns-resolver/0.20.3/trust_dns_resolver/struct.Resolver.html)
//! of trust-dns. Each variant accepts the respective `trust-dns` resolver, so you get enormous
//! freedom and `rsip-dns` shouldn't restrict you in any way.
//!
//! In more advanced scenarios, you might want to build a custom dns client that will implement
//! query caching etc.
