A Rust wrapper for the c-ares library, for
asynchronous DNS requests.
This repository contains three crates:
- c-ares-sys is autogenerated unsafe bindings. It is unlikely that you should want to use this directly.
- c-ares is a safe wrapper around those bindings, with no frills. To use this you must be willing to manage your own event loop.
- c-ares-resolver builds on these crates to offer a friendlier API. This is the crate that most users should likely prefer.
By default, we will use the c-ares installed on your system, if available.
Force use of the vendored c-ares with the vendored feature.
Deny use of the vendored c-ares by removing the default maybe-vendored
feature.
Setting the feature build-cmake will cause the c-ares library to be built
using cmake.
This is significantly faster than the default autotools build on unix
platforms: so if it works for you, you should probably prefer it.
Contributions are welcome. Please send pull requests!
