/*!
This crate provides the runtime library used by parsers that have been generated by the `parol`
parser generator.

In most cases you don't need to understand the inner details of this crate because `parol` generates
all necessary scaffolding and plumping for the typical user automatically.

The most likely used parts are those returned to the user including the error types defined in the
module [errors].

If you use parsers generated in [vanilla mode](https://jsinger67.github.io/VanillaMode.html) you
should understand the types that are handed over to your semantic actions. You will find them in the
module [parser::parse_tree_type].
