A library for interacting with the Domain Name System. The crate contains an ever-growing set of building blocks for including DNS functionality in applications.

Currently, these blocks include:

• basic data structures and functionality for creating and parsing DNS data and messages,
• a simple Tokio-based stub resolver,
• experimental support for DNS client and server transports,
• experimental support for reading data from DNS zone files, storing them in memory and answering queries,
• experimental support for zone transfer, including support for TSIG,
• experimental and as yet incomplete support for DNSSEC signing and validation.

The library is currently under heavy development and additional building blocks and features are being added.

We are trying to maintain a decent balance between being able to use older compiler versions and using new features that improve safety and usability of the crate.

The rust-version given in Cargo.toml is the oldest version that can be used to compile the crate with the minimal versions of all dependencies selected.

You can run cargo nightly update -Z minimal-versions to ask Cargo to select these minimal versions for all dependencies.

This is the minimum Rust version required to build with latest version of all dependencies at time of release. Cargo.lock contains these versions for reference.
