I think we might want to ask other RfL folks about this because it was a name
I suggested actually - and it is actually a name being used in various
bindings already. Alternatively there is from_c(), but I don't actually like
that because as_ref() more closely follows:

https://rust-lang.github.io/api-guidelines/naming.html

Also - in case you're wondering, the naming conflict doesn't ever actually
cause ambiguity issues for the compiler.
