Ladybird Browser Adopts Rust
It's hard to point to what's idiomatic given such low level fp primitives.
Something like https://github.com/composewell/streamly can go very fast and constant memory with 0 allocs.
Once linear types get better support, it would be nice.
Both Rust and Haskell are fairly high-level and I'd bet with proper primitives in both languages it is impossible to reason about register use or performance.

[ANN] Haskell Streamly 0.9.0 Release!
https://github.com/composewell/streamly/issues/1307 seems related, but it was a long time ago. We weren't heavy users anyway, so our streaming philosophy is now "conduit if it's simple and plugging into a conduit-using library, streaming if you're doing complicated things".

Parallel streaming in Haskell: Part 3 - A parallel work consumer
Interesting! Which of the streamly modules is implementing that part? Is it one of the workLoop implementations in Streamly.Internal.Data.Stream.Async?

Haskell Libraries I Love
I want to like streamly, but the API is so huge, yet I feel like I'm doing things on a too low level of abstraction. (And as long as it needs a ghc plugin I doubt it'll become the de facto standard.) Though maybe I just haven't used it enough. It does have great docs at https://streamly.composewell.com/ and they seem to be taking both performance, dependency weight and API design quite seriously.
- Edward Kmett reflects on the benefits of Haskell as a functional programming language - especially at scale.

You missed streamly in your list of alternatives: https://github.com/composewell/streamly/blob/master/docs/streamly-vs-async.md
- It's nice to see how Streamly has now become its own separate beast
