Has anyone made a better man page reader? I'm just using my standard #unix pager here.

C'mon, there a whole generation of new (#rust) CLI unix tools (yay! 👍🏻), surely someone's made an attempt at making man pages easier to read.

I _could_ rewrite it in #Rust… 🤔

I'm doing some #Python (well #ansible), and I find the error messages unclear. Maybe I *want* #Rust's _helpful_ error messages 😜

I wish #Rust had a shorter/less noisey way to `collect` an `Iterator` into a `Vec`. Getting tired of writing `.collect::<Vec<_>>()` so much.

OK, trying to up my #Rust #async game.

I wanna be a good #rust library maintainer, and this is a lot of the little busy work that I would like to see automated.

I've created & uploaded several #Rust crates. Is there an easy & standard way to download/check them all out, and check if all the dependencies are at their latest versions, try to upgrade those deps & run my unit tests?

What's everyone using as a PAGER on #unix now-a-days? `less(1)` is still the default on many systems I use, but I've sometimes uses `most(1)`.

Is there some fancy-pants modern #rust based pager or anything now?

... must resist urge to rewrite more things in #rust

2 new #Rust libraries for yous. Read & write GeoJSON Sequences & JSON Sequences.

Oh Heaptrack is a nice programme to measure & analyze heap memory access of a programme. Works nicely & easily with #Rust code.
I'm finding it quite easily to reduce memory allocations in my code.

Sometime I should give #Rocket a try to build a web app in #Rust. I used to do a lot of #Django. But I'm doing my coding in Rust now.

oooh… #Rust's `std::iter::from_fn(move || { … })` is pretty useful. 🙂

$ ( ls Cargo.toml ; find ./src/ -type f -name '*.rs' ) | entr -r cargo test

this is what I use to automatically run #rust tests when a file is saved

The year is 20XX. Web apps are built in C++ and #Rust with WebAssembly, and desktop apps are built in #JavaScript with Electron.

Grrr! I'm not supposed to get segfaults when writing #Rust programmes! This makes things hard

ah #rust lifetime checker we meet again

"I know I'll just write a quick #Rust programme to proxy my http connections and add the header that I want".

Oh cripes, I forgot hyper's now gone weird with Futures and the like.

I have also learned about `impl Into<Cow<_>>` to accept a `&T` and `T`. Which, in retrospect, should have been obvious to me, but I just didn't put 2 and 2 together.
It should make my #rust code more cleaner/ergonomic!

"Elegant Library APIs in #Rust"
Now this is an interesting guide!
(I learned about the `impl Into<Option<T>>` which looks very useful!)
