On: Thoughts on Rust bloat

[floatboth]

Since when does libc include "rich" things like regex, serialization and http?? Even C++ standard lib is mostly containers and algorithms.

libc is barely a standard library, it's almost nothing.

C might not include those specific examples, but POSIX + libc already include plenty of stuff.

C++ surely does include regex, with serialisation and http scheduled for C++23, or with luck with a TR as intermediate delivery.

Although serialisation depends on static reflection being finalized as well.

Still, it implies C fails, because you don't get POSIX on all available platforms.

I think the definition is meaningless. Rust spends huge amount of resources to test itself and its surrounding ecosystem on tier 1 platforms.

I'm fairly certain regex from c++ std will run like crap, if at all on something with 4MB of RAM.

[pjmlp → Ygg2]

Except the small detail that C's POSIX support is much wider than Rust's tier 1 platforms.

I am fairly certain that without profiling and defining a test configuration for a set of specific C++ compilers / standard C++ library I won't assert anything about std::regex performance with 4 MB of RAM.

Perhaps. But you're comparing a 26 year old standard for a 47 year old language, to a language that's been stable for 4 years.
