Crate reqwest_hickory_resolver 

This crate provides HickoryResolver that implements reqwest Resolve so that we can use it as reqwest’s DNS resolver.

Examples

Init client with HickoryResolver.

use std::sync::Arc;

use reqwest::ClientBuilder;
use reqwest_hickory_resolver::HickoryResolver;

fn init_with_hickory_resolver() -> reqwest::Result<()> {
    let mut builder = ClientBuilder::new();
    builder = builder.dns_resolver(Arc::new(HickoryResolver::default()));
    builder.build()?;
    Ok(())
}

HickoryResolver has cache support, we can share the same resolver across different client for better performance.

use std::sync::Arc;

use once_cell::sync::Lazy;
use reqwest::ClientBuilder;
use reqwest_hickory_resolver::HickoryResolver;

static GLOBAL_RESOLVER: Lazy<Arc<HickoryResolver>> =
    Lazy::new(|| Arc::new(HickoryResolver::default()));

fn init_with_hickory_resolver() -> reqwest::Result<()> {
    let mut builder = ClientBuilder::new();
    builder = builder.dns_resolver(GLOBAL_RESOLVER.clone());
    builder.build()?;
    Ok(())
}
