-David and Lukas share their recent work to migrate rust-analyzer to the new Salsa,
-which gives rust-analyzer persistence, in-query parallelism, raw speed, gc-able interned values with Copy keys, and more.
+rust-analyzer recently migrated to a new version of its incremental computation
+library, Salsa. This has yielded both major and minor performance wins in
+rust-analyzer. In this talk, we’ll discuss the challenges (self-referential
+interning! a 5x memory usage regression!), benefits (parallel autocomplete,
+persistent caches, and near-instant crate graph additions/removals) of new
+Salsa. We’ll also discuss how Salsa works internally and how you can use it in
+your own projects.
