And sure enough, this changed the 8 second expansion time into a 100ms! A bit more info can be found in the PR description here github.com/rust-lang/ru.... This should improve general speed of rust-analyzer in the majority of projects given how pervasive these kinds of macros are in Rust.
proc-macro-srv: Reimplement token trees via immutable trees by Veykril · Pull Request #21097 · rust-lang/rust-analyzer
For macros, rust has the concept of TokenTrees and TokenStreams which are basically a tree-like form of the underlying tokenized input with (){}[] delimiters forming Groups (internal nodes) and all...

so, uh, asking a for a friend: is using pulumi a good idea these days? i like the programming model a lot (and _really_ like the AWS CDK), but it’s strange how many *ex*-pulumi people i know of

i hit this issue in the last two weeks! i’m glad the oxide folks wrote this up
My colleague Dave Pacheco wrote up a great description of a new (to us?) Rust async pathology--"futurelock"--another extremely sharp edge to watch out for, with no particular guardrails. Of course, we'll be talking about it with @bcantrill.bsky.social on Monday's Oxide and Friends

i think one of more surreal moments in the last few weeks was seeing @steveklabnik.com's announcement be featured by @quinnypig.com in Last Week in AWS. like, i started that jj startup! we're not even on AWS at the moment!

TL;DR: I'm going to be leaving @oxide.computer next month, which I'm very sad about. But it's to join @ersc.io , which I'm very excited about!

the thing is, rust can have really fast compile times, but the pervasive use of macros and build scripts obscures that fact. impure proc macros and build scripts are the free parking of the rust ecosystem: benefiting the few at the cost of many
at this point, i think i prefer `go generate` over build dot rs scripts. the latter are too annoying to parallelize and i think codegen is rare enough that being able to run it as an explicit step is worth it for faster/more reliable IDEs
