I've been building a bytecode VM in Rust and recently implemented NaN boxing for value representation. Sharing here for anyone interested.

I needed all VM values (booleans, integers, string pool indices, bytecode references) to fit in 64 bits (stack is Vec).

My implementation encodes 5 distinct types using a 3-bit tag and 32-bit payload, all within a single u64. It also has 15 unused bits, they may be used later for types expansion.

I'm using a 64-bit layout:

• Bits 63-51: Quiet NaN signature (0x7FFC...)
• Bits 50-18: 32-bit payload (integers, string pool indices, etc.)
• Bits 17-3: Unused/ (15 bits)
• Bits 2-0: 3-bit type tag

So it allows me to have 5 tagged types: TRUE_VAL, FALSE_VAL, STRING_VAL, CALLDATA_VAL, U32_VAL

Hey everyone,

Basically the title. I'd like to learn how to make my own drawing program and I'm slightly surprised that I can't seem to find anything about it. No tutorials or discussions about requirements or just general tutorials.

Does anyone have any recommendations on where I could start?

• New CLI flag allows overriding the markdown flavor for a single run
• Options: commonmark, gfm (GitHub Flavored Markdown)
• Useful for testing files against different markdown specifications

This is a small release to support Deku 0.20.0 release. The only incompatibility was an introduced descriptive-errors feature which is explicitly propagated at the moment.

The crate started as support decoding and encoding fixed and variable length unicode strings, but quite soon become more than this.

While there’s some ideas to implement, new ideas and improvements are always welcome.

This Christmas, my wife outdid herself. She knew I loved Rust, so she DIYed me a Ferris. It’s now guarding my desk, judging my unwrap() calls and reminding me to write safer code.

Based on the pattern from here (the instructions are in german)

A new release of Kellnr, the crate registry is out. Kellnr is now a single binary that includes all web resources and config files, making it easier to deploy. As a new feature, web-hooks where added to interact with kellnr from other applications.

Hi everyone,

we, the iceoryx community, just released iceoryx2 v0.8, an ultra-low latency inter-process communication middleware in Rust, with C, C++, Python and with this release, C# bindings.

If you are into robotics, embedded real-time systems (especially safety-critical), autonomous vehicles or just want to hack around, iceoryx2 is built with you in mind.

Check out our release announcement for more details: https://ekxide.io/blog/iceoryx2-0.8-release

And the link to the project: https://github.com/eclipse-iceoryx/iceoryx2
