Trait qiniu_http_client::prelude::Resolver

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

    fn async_resolve<'a>(
        &'a self,
        domain: &'a str,
        opts: ResolveOptions<'a>
    ) -> BoxFuture<'a, ResolveResult> { ... }
}

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<'_>) -> ResolveResult

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>
) -> BoxFuture<'a, ResolveResult>

Available on crate feature async only.

异步解析域名
