The Turbo memoization framework sounds interesting, but I don't see any code samples for what it looks like for Rust users, or how it compares to other Rust memoization/caching libraries…

In several places it is mentioned as a Rust library, but I don't see any links to it. Using google search I'm not finding a Rust library named "Turbo". Is the library open source, or available on crates.io / in a public repo somewhere?

  Right, they link to this docs page when referring to the memoization library: https://turbo.build/pack/docs/core-concepts https://turbo.build/pack/docs/core-concepts And the github link at the top of the page links here: https://github.com/vercel/turbo https://github.com/vercel/turbo but, despite being called "turbo", that seems to actually be the repo for Turbopack (the webpack alternative) not "Turbo" the library. Even digging a bit into the crates, I'm not sure where this supposed library lives: https://github.com/vercel/turbo/tree/main/crates https://github.com/vercel/turbo/tree/main/crates

    The content of that "Core Concepts" page sounds a lot like https://github.com/salsa-rs/salsa https://github.com/salsa-rs/salsa

    The engine here are the creates called "turbo-tasks" and "turbo-tasks-*" extend it with more features. See a bit in https://github.com/vercel/turbo/blob/main/architecture.md#turbo-tasks https://github.com/vercel/turbo/blob/main/architecture.md#tu...

      gotcha, cool – thank you!

Documentation here is one of the areas we need to work on. There's a bit in https://github.com/vercel/turbo/blob/main/architecture.md#turbo-tasks https://github.com/vercel/turbo/blob/main/architecture.md#tu... A small example of code that uses this is https://github.com/vercel/turbo/blob/main/crates/turbo-tasks-env/src/dotenv.rs https://github.com/vercel/turbo/blob/main/crates/turbo-tasks..., which defines how we can load a `.env` file using FS read caching, cached `read` and `read_all` functions, etc.

  Ah, very helpful/interesting – thank you! Seems neat.
