Module ilex::report

Diagnostics and error reports.

This module contains types for generating an error report: a collection of diagnostics that describe why an operation failed in detail. Diagnostics are basically fancy compiler errors: they use SpanIds to present faulty input in context.

The Report type is a reference-counted list of diagnostics, which is typically passed by reference into functions, but can be copied to simplify lifetimes, since it’s reference-counted.
