Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Hey Rustaceans! Got a question? Ask here (49/2023)!
I like config.rs, but I am struggling to overwrite config profiles with environment variables. The desired config is mixed, like .toml
-
Is there a pydantic.BaseSettings equivalent in rust?
Consider config crate. It could be like:
-
How do you store and pass credentials?
I've been using Config most of the time. I also use once_cell to make it a static variable.

How do you manage configuration in rust?
I've enjoyed using this one: https://crates.io/crates/config

Hey Rustaceans! Got a question? Ask here! (28/2022)!
Anyone know of a library like https://github.com/netflix/go-env but for rust? I found https://github.com/mehcode/config-rs but it's just not as simple...
-
How do you merge config in Rust with a default?
I was just in that space today. The config crate has an example you might find useful: https://github.com/mehcode/config-rs/tree/master/examples/hierarchical-env

[ANN] cfg-rs 0.2.0 release
How it differs from config?

Best way to set environment for Rust App
Checking an environment variable is very easy with std::env::var or similar. If you have other bits of configuration that also change—which is typical; things like DB connection strings—you may consider a more full-featured solution like https://docs.rs/config/0.10.1/config/ (pay particular attention to this example, which seems to be very close to what you want: https://github.com/mehcode/config-rs/blob/master/examples/hierarchical-env/src/settings.rs ).

Good way to set up default configurations
It's unfortunate, it looks like there was an attempt to get someone else to maintain it here, but no one ended up really stepping up to the plate.

Rust: Box Is a Unique Type
If you have an object that's !Unpin, then Miri will not apply uniqueness rules to anything containing it [0], including boxes and &mut references. (In the example code, replacing the PhantomPinned with a () will make Miri complain again.) This is considered a temporary (if long-lived) measure to allow async executors to manipulate pinned futures without invalidating all their references and whatnot. Thus, it might be seen as undetected UB, in lieu of a permanent solution.

Fivefold Slower Compared to Go? Optimizing Rust's Protobuf Decoding Performance
That would be true if you used `Vec::clear` too, it doesn't allocate a new vector. My point was that you still end up running Drop implementations with RepeatedField, just not all at once. See https://play.rust-lang.org/?version=stable&mode=debug&editio...

How to Lose Control of Your Shell
That's a valid Unix path, but rust's quoting does nothing to stop it: https://play.rust-lang.org/?version=stable&mode=debug&editio...

Borrow Checking Without Lifetimes
Self-referential structs work fine in Rust and always have.
https://play.rust-lang.org/?version=stable&mode=debug&editio...
The compiler will correctly prevent you from moving the value.
The other way to have a struct that starts out as non-self-referential and then becomes self-referential can be achieved with `unsafe` and `Pin::new_unchecked`, which is how `async {}` is handled.

Improving Interoperability Between Rust and C++
In rust as currently stands: https://play.rust-lang.org/?version=stable&mode=debug&editio...
On the other hand, both this wrapper and yours are counterproductive if the element size is dynamic (e.g. perhaps you're dealing with some nonsense like:)

New Linux glibc flaw lets attackers get root on major distros
Overflow checks turn into two's compliments' wrapping, but that's only considered acceptable because bounds checks are not turned off.

Atomics and Concurrency
I have no idea what you're talking about, but it sounds unnecessarily complicated and why I don't use Rust for any serious work.
This demonstrates the ABA problem in safe Rust: https://play.rust-lang.org/?version=stable&mode=debug&editio...
Substitute the sleep with a combination of doing computation/work and the OS thread scheduler, and you can see how the bug surfaces.
