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.

`toml` vs `toml_edit` (ie `toml` 0.6 is out)
I updated the toml<->json online converter after the ValueAfterTable error has been fixed with toml 0.6. Very nice to see progress on the toml and toml_edit crates.

Error trying to deserialize TOML using Rust/SERDE
use std::fs::File; use std::io::Write; use std::collections::BTreeMap as Map; use serde_derive::{Serialize, Deserialize}; #[derive(Debug)] #[derive(Serialize, Deserialize)] #[serde(tag = "type0")] enum FooBarTwo<'a> { FooBarOne { string1: &'a str }, } #[derive(Debug)] #[derive(Serialize, Deserialize)] #[serde(tag = "type1")] enum FooBarThree<'a> { FooBarFour { string2: &'a str }, } #[derive(Debug)] #[derive(Serialize, Deserialize)] struct FooBarFour<'a> { black: &'a str, #[serde(borrow)] green: FooBarTwo<'a>, #[serde(borrow)] blue: FooBarThree<'a>, } #[derive(Debug)] #[derive(Serialize, Deserialize)] struct FooBarFourList<'a> { // Uasing a Map to workaround a known bug (#303) when using top level Vec // see https://github.com/alexcrichton/toml-rs/issues/303 #[serde(borrow)] foo_bar_six: Map<&'a str, FooBarFour<'a>> } fn main() { let red = FooBarFour { black: "aaa", green: FooBarTwo::FooBarOne { string1: "aaaabbbb" }, blue: FooBarThree::FooBarFour { string2: "ccccccc" }, }; let pink = FooBarFour { black: "aaa", green: FooBarTwo::FooBarOne { string1: "aaaabbbb" }, blue: FooBarThree::FooBarFour { string2: "ccccccc" }, }; let mut white = Map::new(); white.insert("pink", pink); white.insert("red", red); let fbfl = FooBarFourList { foo_bar_six: white }; println!("\nTL: {:?}\n", fbfl); let filename = "./data/test.toml"; let data = toml::to_string(&fbfl).expect("Error serialising fbfl"); println!("\nTL as TOML: {:?}\n", data); let mut f = File::create(filename).expect("Unable to create file"); f.write_all(data.as_bytes()).expect("Error writing data to file"); let toml_in: FooBarFour = toml::from_str(&data).expect("Error deserialising fbfl"); println!("\n{:?}\n", toml_in); }

Introduction to Rust generics [1/2]: Traits
This is especially useful for data deserialization: Just by implementing the Serialize and Deserialize traits from the serde crate, the (almost) universally used serialization library in the Rust world, we can then serialize and deserialize our types to a lot of data formats: JSON, YAML, TOML, BSON and so on...

Hey Rustaceans! Got a question? Ask here! (21/2022)!
It looks like the fields are public now (https://github.com/alexcrichton/toml-rs/pull/455, https://docs.rs/toml/latest/toml/value/struct.Date.html), so just upgrading the crate should do it :-)
-
anyone using rust in production? what do you do?
Pair that with Serde for serialization/deserialization (JSON, TOML, YAML, CSV/TSV, XML, URL query strings, etc.), Figment for configuration, and ignore for filesystem traversal with blacklist support, and Rust is a real joy for writing CLI utilities.

toml_edit v0.3
Added toml-rs-compatible API via the toml_edit::easy module for when developers want to ensure consistency between format-preserving and general TOML work, with one caveat.

Hey Rustaceans! Got an easy question? Ask here (16/2021)!
A quick example off the top of the head of my head is some tests in the toml package. It has a few different approaches. One is to use macros as in parser.rs. In valid.rs and invalid.rs it uses macros to generate a separate test for each input file. This allows you to run just one individual test from the list. These examples aren't perfect, and there are more sophisticated test utilities (like insta) that can abstract the process of "here are a bunch of inputs, test them all".

Reading TOML with default values
I want to read a toml file with default value. I tried toml-rs but it doesn't allow for default values.

Create a Custom GitHub Action in Rust
If you haven't dipped your touch-typing fingers into Rust yet, you really owe it to yourself. Rust is a modern programming language with features that make it suitable not only for systems programming -- its original purpose, but just about any other environment, too; there are frameworks that let your build web services, web applications including user interfaces, software for embedded devices, machine learning solutions, and of course, command-line tools. Since a custom GitHub Action is essentially a command-line tool that interacts with the system through files and environment variables, Rust is perfectly suited for that as well.

Why Does Windows Use Backslash as Path Separator?
Here's an example of someone citing a disagreement between CRT and shell32:
https://github.com/rust-lang/rust/issues/44650
This in addition to the Rust CVE mentioned elsewhere in the thread which was rooted in this issue:
https://blog.rust-lang.org/2024/04/09/cve-2024-24576.html
Here are some quick programs to test contrasting approaches. I don't have examples of inputs where they parse differently on hand right now, but I know they exist. This was also a problem that was frequently discussed internally when I worked at MSFT.

I hate Rust (programming language)
> instead of choosing a certain numbered version of the random library (if I remember correctly) I let cargo download the latest version which had a completely different API.
Yeah, they didn't follow the instructions and got burned. I still think that multiple things went wrong simultaneously for that experience. I wonder if more prevalent uses of `#[doc(alias = "name")]` being leveraged by https://github.com/rust-lang/rust/pull/120730 (which now that I check only accounts for methods and not functions, I should get on that!) so that when changing APIs around people at least get a slightly better experience.

Show HN: Fancy-ANSI – Small JavaScript library for converting ANSI to HTML
Recently did something similar in Rust but for generating SVGs. We've adopted it for snapshot testing of cargo and rustc's output. Don't have a good PR handy for showing Github's rendering of changes in the SVG (text, side-by-side, swiping) but https://github.com/rust-lang/rust/pull/121877/files has newly added SVGs.
To see what is supported, see the screenshot in the docs: https://docs.rs/anstyle-svg/latest/anstyle_svg/
