At OxCon, Ry and I briefly spoke about how to gracefully accommodate the need to inject additional data into rsf so that, for example, one could specify how to format a field, as some AMD registers report things like power or voltage or current in odd units (such as eights of a volt or similar) and it would be nice to normalize those into a standard unit. One could image doing this with something like a snippet of rhai code, but then how would one inject that into an rsf specification?
Ry suggested using attributes; this introduces a familiar
#[attr(id = "string")]
syntax and corresponding parser support for such constucts.
