Delay emission of this diagnostic as a bug.
This can be useful in contexts where an error indicates a bug but typically this only happens when other compilation errors have already happened. In those cases this can be used to defer emission of this diagnostic as a bug in the compiler only if no other errors have been emitted.
In the meantime, though, callsites are required to deal with the "bug" locally in whichever way makes the most sense.

Add a span/label to be included in the resulting snippet.
This is pushed onto the MultiSpan
that was created when the
diagnostic was first built. If you don't call this function at
all, and you just supplied a Span
to create the diagnostic,
then the snippet will just include that Span
, which is
called the primary span.

In case of short messages and a simple suggestion, rustc displays it as a label like
"try adding parentheses: (tup.0).1
"
The message
- should not end in any punctuation (a
:
is added automatically) - should not be a question
- should not contain any parts like "the following", "as shown"
- may look like "to do xyz, use" or "to do xyz, use abc"
- may contain a name of a function, variable or type, but not whole expressions
