Struct DiagnosticMessage 

pub struct DiagnosticMessage(/* private fields */);

A diagnostic message string.

This is, for all intents and purposes, equivalent to a Box<str>. But it does not implement std::fmt::Display. Indeed, that it its entire reason for existence. It provides a way to pass a string directly into diagnostic methods that accept messages without copying that string. This works via the IntoDiagnosticMessage trait.

In most cases, callers shouldn’t need to use this. Instead, there is a blanket trait implementation for IntoDiagnosticMessage for anything that implements std::fmt::Display.
