域名解析的接口

同时提供阻塞接口和异步接口，异步接口则需要启用 async 功能

Required Methods

fn resolve( &self, domain: &str, opts: ResolveOptions<'_>, ) -> Result<ResolveAnswers, Error>

解析域名

该方法的异步版本为 Self::async_resolve。

Provided Methods

fn async_resolve<'a>( &'a self, domain: &'a str, opts: ResolveOptions<'a>, ) -> Pin<Box<dyn Future<Output = Result<ResolveAnswers, Error>> + Send + 'a>>

异步解析域名
