A more convenient API around c-ares, for asynchronous DNS requests.
The c-ares crate provides a safe wrapper around the underlying C library, but it's relatively hard work to use: the user needs to drive the polling of file descriptors according to c-ares demands, which likely involves writing something close to a full-blown event loop.
This crate does that hard work for you so that the presented API is much more straightforward.
API documentation is here.
```rust extern crate caresresolver; extern crate futures; extern crate tokio; use std::error::Error; use futures::future::Future;
fn main() { let resolver = caresresolver::FutureResolver::new().unwrap(); let query = resolver .querya("google.com") .maperr(|e| println!("Lookup failed with error '{}'", e.description())) .map(|result| println!("{}", result)); tokio::run(query); } ```
Further example programs can be found here.
