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?

Broken input sanitization probably.

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

I do, however, hold to the fact that any sudo implementation will be more complicated than doas. Sudo, as a project, has more options and usecases than doas so it also has more posibilities for bugs or misconfiguration for the user.

Fair.

I’m unable to tell what codebase your are refering to with you’re grep arguments, sorry.

sudo-rs

Opendoas has a significantly smaller codebase. It only has 4397 lines of code compared to Sudo-rs’s staggering 35990 lines.

Hmm.

I too love making unaware "Tests Considered Harmful" arguments based on some blind analysis.

Funnily enough, one could easily do some actually potentially useful shallow analysis, instead of a completely blind one, simply by noticing the libc crate dependency, then running:

git grep -Enp -e libc:: --and --not -e '(libc::(c_|LOG)|\b(type|use)\b)'

Ignoring the usage in test modules, use of raw libc appears to be more than you would think from the title. One can also argue that some of that usage would be better served by using rustix instead of raw libc.

Of course authors can counter with arguments why using rustix* is not feasible or would complicate things, and would argue that the use of unsafe+libc is required for this kind of project, and it's still reasonably limited and contained.

And a little bit more informed back-and-forth discussion can go from there.

* Searching for rustix in the sudo-rs repo returned this. So this predictably has been brought up before.

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

Look into Arc, RwLock, and Mutex too.

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

--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

I constantly seem to include something from the docs, only to be told by the compiler that it does not exist, and then I have to open the source for the create to figure out if it’s hidden behind a feature flag.

As others mentioned, the situation is not perfect. And you may need to check Cargo.toml. Maybe even the source.

But as for the quoted part above, the docs should definitely indicate if a part of the API is behind a feature. Let's take rustix as an example.

Here is the module list:

Here is the view from inside a module:

Here is the view from a function page:

This is also true for platform support. Take this extension trait from std:

Now, it's true that one could be navigating to method docs in the middle of a long doc page, where those indicators at the top may be missed. But that's a UI issue. And it could be argued that repeating those indicators over and over would introduce too much clutter.
