I too used to program in C++. Every Monday morning, it was the same routine: as I enter the office, the stench of decaying bodies is overwhelming. Yet I must gather my strength to collect and identify the people killed over the week-end by C++ memory safety issues gone unchecked. Once that's done, I start my daily Scrum standup at 11 and I start coding a bit. First build at 11.30, first segfault at 11.35. Then it's pretty much the same routine, after lunch I read the Valgrind and ASan reports, spotting which one of the hundreds of new safety issues it identified might be an easy fix. I go back home riding my bicycle around 7pm, making sure to avoid the cars trying to crash against me due to segfaults. Sometimes I cry at night thinking about all that.

And then one day I found Rust, and all those problems went away. I can now write fearless code, and I don't have to endure the stench of rotting bodies anymore.

True story.

I have to say, Rust is looking more mature lately. I wrote a little RSS reader in Rust two years ago, and it was a pain to get all the library version dependencies lined up. Yesterday I recompiled it. No more need for version pinning or Github references; it just worked with a default cargo.toml file. Two years ago there was too much "only works in nightly" or "you need to use this version of that library". Progress.

Any progress on a C++ to Rust converter? Not a "transpiler". Something with enough smarts to figure out when to use native Rust arrays, not "offsets" to imitate pointer arithmetic. I'm surprised that one of the big C++ users, like Google, doesn't have a group doing that.

Something like the cxx crate[1]? You specify your shared objects between C++ and Rust, and it spits out code for both sides.

The guy who maintains it said in the reddit thread[2] about this same topic that the Google people have been sending him good PRs, which is presumably related to integrating Rust into Chrome.
