For the last LPC talk, I got some simple numbers with and without `syn` (and in the past with and without `alloc`), plotted them and added an exponential trendline for fun -- slides 21 to 28:

Nothing fancy, but one summary is that the Rust code more than quadrupled in a year (and that is without counting vendored code).

That is an astonishing rate of growth. Actually, it isn't just the exponential curve that's impressive but the total LOC in tree as well. I often see mention of rust code that can't be upstreamed yet because of missing plumbing -- which gave me the impression that the rate of ingress had been fairly slow. This thread makes it sound like ~10% of new code in a release is now rust -- that's mind blowing.
