Externs are symbols that are expected to be defined by package importers
|
|
before linking.
|
|
Rather than explicitly declaring extern symbols,
|
|
these templates provide more human-readable abstractions.
|
|
|
|
|
|
Note that when defining extern classifications with
|
|
\ref{_classify-extern_},
|
|
if specifying a yield,
|
|
the dimensionality is~$1$ unless otherwise provided.
