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.

-🎄- 2022 Day 13 Solutions -🎄-
I used yhirose's PEG (parsing expression grammar) libraryfor parsing.

What are some cool modern libraries you enjoy using?
By the same author, https://github.com/yhirose/cpp-peglib is also very nice.
-
A Good Tool for Resuming Parsers?
Most of the research into this sort of incremental and differential parsing unsurprisingly looks to be in the Haskell community, but I was hoping that someone here might know of some C++-friendly tools that might support generating parsers that support interruption and resuming. cpp-peglib looked really promising, but its parsers don't look like they can be engaged from any but the initial state.

What even is a JSON number?
Oh wow. So serde_json doesn't roundtrip floats by default, it uses some imprecise faster algorithm https://github.com/serde-rs/json/issues/707
Good thing there's msgpack I guess.

I pre-released my project "json-responder" written in Rust

Flow Updater JSON Creator
Serde JSON, an extension of the serde crate that enables the serialization and deserialization of Rust structs.
-
A Simple CRUD API in Rust with Cloudflare Workers, Cloudflare KV, and the Rust Router
To serialize and deserialize data, we'll employ the popular serde crate along with serde_json. This will allow us to easily convert between Rust types and JSON when working with API requests and responses. For async operations we'll use the Rust futures crate.

Building a Rust app with Perseus
From the Cargo.toml file above, we can see that the Perseus version at the time of publication is 0.4.2 and has the following dependencies that are common to both the engine side (server-side) and client side of a Perseus application: sycamore, serde, and serde_json.

Müsli - An experimental binary serialization framework with more choice
Number parsing uses a fairly naive but uses a lossless algorithm in musli-json. In serde_json they use a fork of lexical I haven't wrapped my head around. I wanted something simple to start with.
-
How can I deserialise this value?
Your best best would be to use an enum. Either your own or something like the one from serde_json depending on what you are trying to do.
-
Spotting and Avoiding Heap Fragmentation in Rust Apps
Don't do that if you care about memory usage. In your toy program, I wouldn't be surprised if memory usage was a lot better if you used Box instead. (even if it doesn't look like it, you can handle almost all the use cases of serde_json::Value with it, often not much less convenient)
