Crate parol_runtime

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 you should understand the types that are handed over to your semantic actions. You will find them in the modules parser::parse_tree_type and parser::parse_tree_stack_entry.
