Lib.rs

Generally, changes in this crate require care because forward and backward compatibility is important.

This is important throughout the crate but especially in the src/do_not_modify folder. See the readme there for more detail.

lib.rs:

This crate contains the interface between a runner and the core library It is very important that no backward-incompatible changes are made within one major version of the runner interface

Each runner is built against one version of this crate. The core library is built against all major versions of this crate
