The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
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.

Is there comptime reflection in Rust proc-macro?
You can make the code generated by your macro add to a distributed slice from the linkme crate and you can use values from that slice at compile time.
-
Match against function/symbol names
there was linkme which i think can be used for what you describe. from your perspective you get a slice and can put functions in it at link time with an attribute macro.

dtolnay/inventory got archived, is there an alternative ?
@dtolnay I noticed you just archived the repos for inventory, linkme, gflags, and typetag, which I assume implies a deprecation.
-
Is it possible to scan all structs/functions that have a specific #[macro] ?
An alternative to inventory which I find better for a lot of purposes: https://github.com/dtolnay/linkme

What's your favourite under-rated Rust crate and why?
I like dtolnay's inventory or linkme crates to register items in a central list, just using decentralized annotations.

How to save a Box<dyn Trait> varialble to a local file?
The error message is pretty clear: this behavior has just not been implemented in typetag. There's even an open issue discussing why this is difficult to do.
- TypeTag/inventory/linkme are unarchived
-
Mapping between JSON and a list of structs which implement a trait
So something like this then? https://github.com/dtolnay/typetag

Ideal way of converting trait objects into other trait objects
My thought process is I will use Serde deserialization and typetag so that I can get a Vec> from the configuration file. Then I just have to figure out a way to construct Vec> from it and I will be set.

Question on the future of inventory, typetag, linkme, ctor, and related crates affected by #47384
I am using the typetag crate in a project. I have a use case that is very similar to the example laid out in the crate's documentation. Given the issue being discussed in #47384, it seems evident that using typetag would be a bad idea, for the time being.

Instantiate a struct from TypeId
You're right, you'd basically need some kind of hashmap, that gets initialized before the application starts. It might work with a similar approach like in typetag. typetag is a library that allows (de)serializing into/from dynamic objects. But it requires annotating each type you're planning to use with an attribute.

Untapped potential in Rust's type system
This allows me define methods on both borrowed (`Message<&str>`) and owned (`Message`) versions without issues. When remaining inside the process, the borrowed version is passed around and when sent across the process boundaries I can deserialize it to an owned version. This problem prevent me from using Typetag and I am still not sure how it should be solved.

Serialize arbitrary struct using traits?
ended up using https://github.com/dtolnay/typetag which uses this under the hood, so thanks!
