As a user of any higher level data structures there's no way for you to know what happens to values passed though. You're absolutely right that if you were using nothing but the stdlib you always know (mostly) that you are explicitly calling forget.
The problem is that you don't know that to be the case as the consumer of a library without a thorough audit of the library. Especially when dealing with ffis things get very muddy very fast.
As much as I'd love for this to happen, I'm uncertain if editions are robust enough for this to happen. I feel like, in 10 or so years, there needs to be a breaking edition addresses some of these concerns.
It's super hard to get everything right the first time and I think rust has done an excellent job of ensuring that we're moving forward incrementally but a leak trait makes things so much nicer in the long run.
Leaking might be safe, but not knowing that somewhere in the stack you're forgetting values is so hard to know when you want to build very long running programs

TL;DR: This post describes LLVM optimization remarks that can useful to help the compiler better optimize your programs. If you want to analyze remarks generated from compiling Rust programs, you can use the cargo-remark tool.
Empowering everyone to build reliable and efficient software.
Initial versions of the EndBASIC Service, and therefore initial versions of EndTRACKER, used dynamic dispatch to support abstract definitions of system services such as the database they talk to and the clock they use. This looked like a bunch of Arc objects passed around and was done to support ext...

I’m excited to share with y’all that Sniffnet is one year old today! The last 365 days of my life have been almost totally dedicated to this project and I’ve learned a lot along the way. On August ...
Yes, as far as I'm aware this is only focusing on compile times.
Last week I requested help with some data analysis of the Rust compiler.
It has been quite a while since the last progress report. A ton of progress has been made since then, but I simply didn’t get around writing a new progress report. There have been 639 commits since the last progress report. This is significantly more than the last time given how long there has been ...
