This might be an incremental bug. Try
cargo cleanthen rebuilding.Red-exe-Engineer commentedon Mar 2, 2023
Actually, I got it working and now that I paste the old code it works... Rust just got a hole lot weirder.
workingjubilee commentedon Mar 2, 2023
All compilers have "internal compiler errors" from time to time. These are errors due to input code that the compiler didn't expect and didn't have a more useful response prepared for. In Rust's case they're most often due to "incremental compilation", where you compile some code and the compiler writes some "intermediate artifacts" (files containing partially compiled code and some notes on what is in the files and where they came from) to your filesystem, so that when you next run the compiler, the previous result is reused. However, this requires us to correctly handle something that has dashed many a programmer upon its rocks:
Cache invalidation.
We could remove the incremental compilation features, and thus not produce these occasional errors, but last time we checked, while it would halve the time on some builds, most builds would be 5 times slower. As mentioned,
cargo cleanfixes most of them, but thank you for reporting![-]I'm new to Rust, how long might this take to get resolved?[/-][+]incr-comp: thread 'rustc' panicked at 'attempted to read from stolen value: rustc_middle::mir::Body'[/+]cjgillot commentedon Apr 13, 2023
