I spent some time working on it, and it looks like we are supposed to install rust-analyzer-proc-macro-srv into /libexec. I've followed upstream's recommendation and added it to the "out" output, albeit manually because there isn't an install target for it. I've also wrapped rust-analyzer with it, and when rust-team is merged into master again (eventually) it should be working. In the meantime, if you want to try it out, 'guix time-machine --branch=rust-team -- shell rust-analyzer' should provide a rust-analyzer wrapped with rust:src and with rust-analyzer-proc-macro-srv. -- Efraim Flashner <efr...@flashner.co.il> אפרים פלשנר GPG key = A28B F40C 3E55 1372 662D 14F7 41AA E7DC CA3D 8351 Confidentiality cannot be guaranteed on emails sent or received unencrypted
