选择 IP 地址接口

还提供了对选择结果的反馈接口，用以修正自身选择逻辑，优化选择结果

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 choose( &self, ips: &[IpAddrWithPort], opts: ChooseOptions<'_> ) -> ChosenResults

选择 IP 地址列表

fn feedback(&self, feedback: ChooserFeedback<'_>)

反馈选择的 IP 地址列表的结果

Provided Methods

fn async_choose<'a>( &'a self, ips: &'a [IpAddrWithPort], opts: ChooseOptions<'a> ) -> BoxFuture<'a, ChosenResults>

Available on crate feature async only.

异步选择 IP 地址列表

该方法的异步版本为 Self::async_choose。

fn async_feedback<'a>( &'a self, feedback: ChooserFeedback<'a> ) -> BoxFuture<'a, ()>

Available on crate feature async only.

异步反馈选择的 IP 地址列表的结果
