Maybe it's better to have just one line for this. Is the performance impact significant compared to format!()?

core::fmt::write makes up 17.5% of all CPU cycles used in svd2rust so I'm looking for ways to reduce its usage in addition to trying to have canned code available instead of regenerating everything with every invocation.

I think this code is not faster.

It's completely in the noise.

What about merging into one line? It looks more readable and should be (insignificantly) faster:

let readerdoc = String::from("Reader of field `") + &f.name + "`";

If you prefer to leave things as they are, just bors r= me

I have other plans with the quoted field name. ;) Moving out the readerdoc was just to get rid of the three separate definitions.

Still working on figuring out how to make proc_macro2 play ball with respect to being able to pre-generate the TokenTrees/TokenStreams and simply change the field names
