IMHO they created type annotations, not a type system and how you use the type annotations to indicate a type system is inconsistent and incomplete (e.g. NoneType vs. None for inconsistency and a lot of mess related to mataclasses (e.g. Enu

It's even worse (for python). TS might transpile to JS and can always be split into a js and type annotation file but is it's own language developed in tandem with the type check based on a holistisch approach to find how to type

Germany (and many parts of the EU) have: - _way_ higher requirements for "safe normal care usage skill" then the US - way higher care safety requirements (as in what cars are allowed to be on the street) - a different driving rule

yeah I mean you are basically stuck with a few options - use C/C++ focused debugers with a rust plugin or similar (okay, not not compared to idk. debugging python in PyStorm) - rely on tracing/logging and errors reported (which mi

To be clear my point isn't that rust has no problems with what I call remote build cache, other might call shipping build artifacts etc. it _has_ issues there, which can be improved on, people are working on it, just kinda slowly but t

the thing is: codegen-units defaults to 16 in release builds, and by far the most time in the "passes" list is spend in LLVM passed (which is was codegen-units parallelizes),so most times it shouldn't be stuck with 1 high loa

yesn't codegen in the OP article is machine gode generation (i.e. running LLVM) It's semantically kinda like having a single 100k file, but because rust knows it often generates huge "files" there is a splitting step, so

codegen units is quite the same as the `-j` flag cargo has the `-j` flag and defaults it to #cpus (logical cpus), so it's by default using the most times most optimal choice there And this will parallelize the compilation of all "

you are missing a lot of things - Compilation is an inherently hard to parallelize thing, and not just hard to parallelize but there are a lot of trade offs. This trade offs aren't even rust specific (i.e. C,C++, etc. are affected as m

The main issue here is: - in rust one semantic compilation unit is one crate - in C one semantic compilation unit is one file There are quite a bunch of benefits in the rust approach, but also drawbacks, like huge projects have to be split

One thing I often see pop up in larger projects, which in the article is likely the fault of way to large symbols, is overuse of generics/type state/etc. Or you could formulate this as needless obsession with not using `dyn`. And
