Enum Item 

pub enum Item {
    Single(Box<Node>),
    Multiple(Vec<Item>),
    ImportError(PathBuf, Error),
}

An abstraction above Node to implement import

Variants

Single(Box<Node>)

A single item in the current file

E.g. Node::Assignment

Multiple(Vec<Item>)

The expansion of a import statement

Contains all items from the importd file.

ImportError(PathBuf, Error)

Encapsulates errors on import

We can’t use normal Rust error handling techniques due to abstraction by rust-peg. Instead, embed an Item::ImportErrors on a import error.
