A fast B+ Tree implementation that uses integer keys.
The API is similar to the standard library's BTreeMap with some significant differences:
* Lookups and insertions are 2-4x faster than BTreeMap.
* BTree can optionally be used as a multi-map and hold duplicate keys.
* Keys must be integer types or convertible to integers via the BTreeKey trait.
* The maximum integer value is reserved for internal use and cannot be used by keys.
* Elements in the tree are ordered by the integer value of the key instead of the Ord implementation of the keys.
* Cursors can be used to seek back-and-forth in the tree while inserting or removing elements.
* Iterators only support forward iteration.

YouTube Gravitational field of Bad Apple!! using Finite Element Method I have a 2D Finite Element Method program that calculates gravitational potential and gravitational acceleration for a mass distribution + portals (see my video about how portals teleport gravity: https://www.youtube.com/watch?v=DydIhwLrbMk). What I did…Eurydice is a compiler from Rust to C that aims to produce readable C code.
Having a backwards-compat scenario where Rust can be compiled to C serves several purposes.
<...>
3. It allows for a census of problematic scenarios. By making the Rust version the default (and putting the fallback C behind a--write-us-an-emailflag), there is finally a way to enumerate those mythical users who cannot switch to Rust just yet.

Блог* The (successful) end of the kernel Rust experiment The topic of the Rust experiment was just discussed at the annual Maintainers Summit. The consensus among the assembled developers is that Rust in the kernel is no longer experimental — it is now a core part…
At the 2025 Maintainers Summit, a session was held to evaluate the state of that experiment, and to decide whether the time had come to declare the result to be a success. The (arguably, unsurprising) conclusion was that the experiment is indeed a success, <...>
The DRM (graphics) subsystem has been an early adopter of the Rust language. It was still perhaps surprising, though, when Airlie (the DRM maintainer) said that the subsystem is only ""about a year away"" from disallowing new drivers written in C and requiring the use of Rust.
