Struct Variable 

struct Variable {
    declared: BTreeSet<(String, String)>,
    documentation: Vec<String>,
    read: BTreeSet<String>,
    written: BTreeSet<String>,
}

One variable, and everything the code says about it.

Every provenance set is a set of file paths, not of line numbers: reporting a line would mean turning on proc-macro2’s span-locations feature for the whole workspace, and a repository-relative path is enough to walk to — a grep for the variable’s own name finds the line, and the path is what a page may cite anyway.

Fields

declared: BTreeSet<(String, String)>

Where a const declares its name, with the constant’s own identifier.

documentation: Vec<String>

The doc comment on that constant, as paragraphs.

read: BTreeSet<String>

The files that read it.

written: BTreeSet<String>

The files that set it on a child process.
