A sizeable chunk of Firezone's Rust components deal with parsing, manipulating and emitting DNS queries and responses. The API surface of DNS is quite large and to make handling of all corner-cases easier, we depend on the `domain` library to do the heavy-lifting for us. For better or worse, `domain` follows a lazy-parsing approach. Thus, creating a new DNS message doesn't actually verify that it is in fact valid. Within Firezone, we make several assumptions around DNS messages, such as that they will only ever contain a single question. Historically, DNS allows for multiple questions per query but in practise, nobody uses that. Due to how we handle DNS in Firezone, manipulating these messages happens in multiple places. That combined with the lazy-parsing approach from `domain` warrants having our own `dns-types` library that wraps `domain` and provides us with types that offer the interface we need in the rest of the codebase.

Connlib
Firezone's connectivity library shared by all clients.
Building Connlib
You shouldn't need to build connlib directly; it's typically built as a dependency of one of the other Firezone components. See READMEs in those directories for relevant instructions.
