The exact code formatting we use is not as important as uniformity. Since we do not use tooling to control the formatting we have to be vigilant ourselves. Recently I (Tobin) changed the way default type parameters were formatted (arbitrarily but uniformly). Turns out I picked the wrong way, there is already a convention as shown in the rust documentation online (e.g. [1]).
Use 'conventional' spacing for default type parameters. Make the changeacross the whole repository, found using

Note
I also audited our whole stack to make sure I had not botched this anywhere else. Apologies for the code churn.
