Module diagnostic 

What a tool finds wrong — reading a document, building a mod, serving a request — each as one record: what it is (a code), how bad, what’s wrong and where (a file, its line and column, a value’s path in it). The one kind of problem every tool says and every tool reads.

Structs

Diagnostic

One thing found.

Errors

Every problem found reading a document, in its order.

Enums

Code

A diagnostic’s kind: one of this crate’s Problems, or a tool’s own code (E0308, a lint’s name), kept as an Atom. Written as its code in every form.

Problem

What’s wrong with a value, as this crate finds it: each a stable code (SD…) tools can match on.

Severity

How bad it is.
