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.

Müsli - An experimental binary serialization framework with more choice
And before you ask: This only provides partial zero-copy support in strings and byte arrays like serde. But it's not like rkyv which constructs validated references into the data.

A new major version of jql has been released
Regarding JSON, what kind of other implementation do you have in mind? I've seen e.g. `rkyv` which looks really neat (https://github.com/rkyv/rkyv/issues/85). So far `serde_json` is providing a clean surface API but maybe there's best solution?

My negative views on Rust
Thank you for your concern. I've done plenty of projects that go beyond a "Hello World" such as a GPU accelerated password cracker. I am starting soon a C++/Rust job. I already contributed to codebases I didn't write.

Hey Rustaceans! Got a question? Ask here! (37/2022)!
rkyv is awesome because it supports full zero-copy deserialization. You can serialize your HashMap to a file. Later you can directly use the HashMap from the file without creating and populating a new HashMap in memory (rkyv directly indexes into the raw bytes). For even faster access times you can even mmap the file.

Bizarre memory leak caused by tokio runtime
I had the same problem when trying to deserialize a big struct with rkyv: see rkyv#277.

Advice for the next dozen Rust GUIs
Any chance of working with zero-copy deserialization frameworks? like https://github.com/rkyv/rkyv or capnproto

Pijul 1.0 Beta
Hi, you seem to know a bit about Sanakirja!
It stores 4kb blobs, right? Does Pijul first parses the data (copying it to other allocations), or uses the data as is? I mean, there are some libraries like cap'n'proto[0] and rkyv[1] that can directly use the file contents as an in-memory data structure, I was wondering if Pijul did anything like that.
I mean, is this btree page [2] stored exactly like this on disk, and does Pijul exploits that to avoid further copying data?
(I guess there's a trouble with compression there: to decompress you really need to write in another buffer)
Also, is the I/O done with something that prevent userspace copies like mmap or io_uring, or does it eventually calls read() to copy the data to its own buffer?
I want to build something like Sanakirja, but with those features, so I'm wondering if there's any overlap.

Is there a library like Serde but which makes it easy to mutate serialized data stored in a [u8] or Vec<u8>?
I think https://github.com/rkyv/rkyv does this. Also capnproto like was mentioned here, and perhaps https://docs.rs/zerocopy/0.6.1/zerocopy/index.html too

rkyv 0.7: Endian-agnostic types, `no_std` validation, performance improvements, github sponsors and more!
It's been two months since the last major rkyv release, and three months since the last major feature release. After all that time, I'm proud to announce that rkyv 0.7 is finally out!

After roughly two months of work, rkyv 0.5 is finally out!

Writing an OS in Rust to run on RISC-V
Xous, the OS that runs on the precursor, may be of interest to look at too:

It is written in Rust and is targeted for a RISC-V

Is there any reliable guide for creating an operating system in Rust?
In addition to phil-opp and redox, there's the Betrusted project's Xous kernel, which runs on a RISC-V core that runs on an FPGA. There's even an Xous Book.

Another Vulnerability in the LPC55S69 ROM
You might be interested in Precursor and the Betrusted Platform.
https://www.crowdsupply.com/sutajio-kosagi/precursor
They are trying to have an hardware platform that can be inspected and it is based on an FPGA with a RISC-V Softcore.
Its by Bunnie, and he great talks about the choices and why he made them:
Keynote: Precursor - Trustable Open Hardware for Everyday Use - Bunnie Huang (https://www.youtube.com/watch?v=Fw5FEuGRrLE)
They are also doing their own Rust Message passing OS called Xous that might be of interest.

Kerla: Monolithic kernel in Rust, aiming for Linux ABI compatibility
There are more good efforts, the BeTrusted guys are working on Xous, its a microkernel for a phone like device called the Precurser.
https://github.com/betrusted-io/xous-core
As a embedded service processor OS for a big server rack, Oxide Computer is working on 'HubrisOS'. They seem to have not released it yet, but that will be open sourced.
https://github.com/oxidecomputer
Those are two efforts where I know real resources are going into.
