Trait qiniu_objects_manager::prelude::Resolver

pub trait Resolver: Debug + Sync + Send {
    fn resolve(
        &self,
        domain: &str,
        opts: ResolveOptions<'_>
    ) -> Result<ResolveAnswers, Error>;

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

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

异步解析域名
