It was stabilized in 2019 by accident: https://twitter.com/m_ou_se/status/1396827152859942921 https://github.com/rust-lang/rust/pull/79270

An important one is missing from this overview: using a const. This is sometimes useful, because it does not require the type to be Copy; only that the value is a constant: const EMPTY: String = String::new(); let a: [String; 10

`T: 'a` means that you may keep values of type T around for lifetime 'a, but not that they will . So `T: 'static` means that you may keep values of that type around forever, as they do not refer to anything that doesn&#x27

Imports work fine. The main reason I wrote this, was to be able to use the Python matplotlib library in Rust: https://twitter.com/m_ou_se/status/1120577172438233088

It doesn't translate Python to Rust or anything like that, it uses CPython both to compile to Python bytecode and to run it. It doesn't launch a separate interpreter, the interpreter is used as a library, so runs in the same proce

It uses the same Python interpreter, but each macro invocation is considered its own module. A later version of the crate will have the possibility to keep the context around to be re-used by a later invocation such that, for example, you d

In Python, all data (even simple integers) are all allocated on the heap. ToPyObject makes a deep copy of everything, converting everything to `PyObject` on the heap, so all data is owned. The numpy crate helps if you need to convert large

Matplotlib was one of the reasons I made this. Works just fine: https://github.com/dronesforwork/inline-python/blob/aebabc88...

At work, we make high performant drone control systems in Rust. But for testing and debugging, we simply use Matplotlib (a Python library) to make plots of simulations, etc. So we prefer Rust for the control systems themselves for the speed

Yes, this was our main worry as well. At first we switched to Rust only for the lower level code, the parts that interfaces with sensors and the motors, that do the data logging, our inter process communication library, etc. The part with t

Yes! I'm founder of a start-up (about 10 employees now) that makes flight controllers for Drones, and all the software that runs on them is written in Rust. We don't use STM chips though. Since the way we do state estimation and f

C does not have a modulo operator. It has a remainder operator, which works perfectly fine. Calling C's `%` a 'broken modulo operator' is like calling `+` a 'broken minus operator'. Quite a few languages have separa

Some do. More are active on Reddit. But new proposals can come from anyone. Though, before writing and submitting any, check on the public std-proposals mailinglist if your idea would get any traction. See https://isocpp.org&#x2F
