Blocking work instead of comms.
And being open about it.
How obnoxious!

We already knew it was from mastoclowns, for mastoclowns.
The details and which “e-celebs” are involved is immaterial.
No one relevant (or merely sane) cared, cares, or will ever care about that scene’s rage-circlejerk choice of the day.

Regarding Cargo.lock, the recommendation always was to include it in version control for application/binary crates, but not library ones. But tendencies changed over time to include it even for libraries. If a rust-toolchain file is tracked by version control, and is pinned to a specific stable release, then Cargo.lock should definitely be tracked too [1][2].

It’s strictly more information tracked, so there is no logical reason not to include it. There was this concern about people not being aware of --locked not being the default behaviour of cargo install, giving a false sense of security/reliability/reproducibility. But “false sense” is never a good technical argument in my book.

Anyway, your crate is an application/binary one. And if you were to not change the "*" dependency version requirement, then it is almost guaranteed that building your crate will break in the future without tracking Cargo.lock ;)

• Don’t use "*" dep version requirements.
• Add Cargo.lock to version control.
• Why read to string if you’re going to base64-encode and use Vec<u8> later anyway?

Here is an originally random list (using cargo tree --prefix=depth) with some very loose logical grouping. Wide-scoped and well-known crates removed (some remaining are probably still known by most).

My quick notes which are tailored to beginners:

Use Option::ok_or_else() and Result::map_err() instead of let .. else.

• let .. else didn’t always exist. And you might find that some old timers are slightly triggered by it.
• Functional style is generally preferred, as long as it doesn’t effectively become a code obfuscater, like over-using Options as iterators (yes Options are iterators).
• Familiarize yourself with the ? operator and the Try trait

Type inference and generic params

let headers: HashMap = header_pairs
        .iter()
        .map(|line| line.split_once(":").unwrap())
        .map(|(k, v)| (k.trim().to_string(), v.trim().to_string()))
        .collect();

(Borken sanitization will probably butcher this code, good thing the problem will be gone in Lemmy 0.19)

Three tips here:

1. You don’t need to annotate the type here because it can be inferred since headers will be returned as a struct field, the type of which is already known.
2. In this pattern, you should know that you can provide the collected type as a generic param to collect() itself. That may prove useful in other scenarios.
3. You should know that you can collect to a Result/Option if the iterator items are Results/Options. So that .unwrap() is not an ergonomic necessity 😉

Minor point

• Use .into() or .to_owned() for &str => String conversions.
  • Again, some pre-specialization old timers may get slightly triggered by it.

make good use of the crate echo system

• It’s important to make good use of the crate echo system, and talking to people is important in doing that correctly and efficiently.
  • This post is a good start.
  • More specifically, the http crate is the compatibility layer used HTTP rust implementations. Check it out and maybe incorporate it into your experimental/educational code.

Alright, I will stop myself here.

Broken input sanitization probably.

Issue will thankfully no longer exist in the next lemmy release.

lemmy deleted everything between the “less than” character and “>”.

Lemmy also escaped the ampersands in their comment’s link 😉

Isn’t broken sanitization great!

Next Day Edit: Sorry. Forgot to use my Canadian Aboriginal syllabics again. Because apparently it’s too hard to admit HTML-sanitizing source markdown was wrong!

One thing that irks me in these articles is gauging the opinion of the “Rust community” through Reddit/HN/Lemmy😉/blogs… etc. I don’t think I’d be way off the mark when I say that these platforms mostly collectively reflect the thoughts of junior Rustaceans, or non-Rustaceans experimenting with Rust, with the latter being the loudest, especially if they are struggling with it!

And I disagree with the argument that poor standard library support is the major issue, although I myself had that thought before. It’s definitely current lack of language features that do introduce some annoyances. I do agree however that implicit coloring is not the answer (or an answer I want to ever see).

Take this simple code I was writing today. Ideally, I would have liked to write it in functional style:

    async fn some_fn(＆self) -> OptionᐸMyResᐸVecᐸu8ᐳᐳᐳ {
        (bool_cond).then(|| async {
            // ...
            // res_op1().await?;
            // res_op2().await?;
            // ...
            Ok(bytes)
        })
    }

But this of course doesn’t work because of the opaque type of the async block. Is that a serious hurdle? Obviously, it’s not:

    async fn some_fn(＆self) -> OptionᐸMyResᐸVecᐸu8ᐳᐳᐳ {
        if !bool_cond {
            return None;
        }

        let res = || async {
            // ...
            // res_op1()?;
            // res_op2()?;
            // ...
            Ok(bytes)
        };

        Some(res().await)
    }

And done. A productive Rustacean is hardly wasting time on this.

Okay, bool::then() is not the best example. I’m just show-casing that it’s current language limitations, not stdlib ones, that are behind the odd async annoyance encountered. And the solution, I would argue, does not have to come in the form of implicit coloring.

Practically speaking, you don’t have to.

Your executor of choice should be doing tokio compat for you, one way or another, so you don’t have to worry about it (e.g. async-global-executor with the tokio feature).

async-std is dead.

exa (which OP’s readme says eza is built on) supports creation times. Actual creation time (the “Birth” line in stat output), not ctime.

I would bad mouth Axum and Actix just because of the overhype. But then, the latter is powering this very platform, and the former is used in the federation crate examples 😉

So let me just say that I tried poem and it got the job done for me. Rusty API. Decent documentation. And everything is in one crate. No books, extension crates, and towers of abstractions needed.

I try to avoid tokio stuff in general for the same reason, although a compatible executor is unfortunately often required.

Look into Arc, RwLock, and Mutex too.

Later, check out parking_lot and co. and maybe async stuff too.

From your list, I use bat, exa and rg.

delta (sometimes packaged as git-delta) deserves a mention. I use it with this git configuration:

[core]
  # --inspect-raw-lines=false fixes issue where some added lines appear in bold blue without green background
  # default minus-style is 'normal auto'
  pager = "delta --inspect-raw-lines=false --minus-style='syntax #400000' --plus-style='syntax #004000' --minus-emph-style='normal #a00000' --plus-emph-style='normal #00a000' --line-buffer-size=48 --max-line-distance=0.8"

[interactive]
  diffFilter = "delta --inspect-raw-lines=false --color-only --minus-style='syntax #400000' --plus-style='syntax #004000' --minus-emph-style='normal #a00000' --plus-emph-style='normal #00a000' --line-buffer-size=48 --max-line-distance=0.8"

[delta]
  navigate = true  # use n and N to move between diff sections
  light = false    # set to true if you're in a terminal w/ a light background color (e.g. the default macOS terminal)

[merge]
  conflictstyle = diff3

Still on 0.17.4 btw.

--all-features doesn’t work with that particular crate because two of the features conflict with each other. The features list in my command is the one used for docs.rs from the crate’s Cargo.toml.

are there any hurdles or other good reasons to not just adding this to every create?

I’m no expert. But my guess would be that many crate authors may simply not be aware of this feature. It wasn’t always there, and it’s still unstable. You would have to reach the “Unstable features” page of the rustdoc book to know about it.

Or maybe some know about it, but don’t want to use an unstable feature, or are just waiting for it to possibly automatically work without any modifications.

Of course, I would assume none of this applies to the embassy devs. That Cargo.toml file has a flavors field, which is something I’ve never seen before 😉 So, I’m assuming they are way more knowledgable (and up-to-date) about the Rust ecosystem than me.

So, this is being worked on. But for now, that crate needs this line in lib.rs

#![cfg_attr(docsrs, feature(doc_auto_cfg))]

And this line in Cargo.toml’s [package.metadata.docs.rs] section:

rustdoc-args = ["--cfg", "docsrs"]

With these changes, feature gating will be displayed in the docs.

To replicate this locally:

RUSTDOCFLAGS='--cfg docsrs' cargo doc --features=nightly,defmt,pender-callback,arch-cortex-m,executor-thread,executor-interrupt
