The difference between an arena allocator and RAII deallocation is that the latter is eager. This is the whole point: the problem that an arena allocator attempts to solve is to presume that fine-grained freeing is slow and thereby solve th

What tialaramex is saying is that, in the Java code, there will be a separate allocation for every `a_goose` that gets added to the ArrayList, whereas the Rust code only has a single allocation for the backing storage for the Vec (not count

There are several libraries for doing arena allocation in Rust, e.g. bumpalo: https://crates.io/crates/bumpalo , see the documentation for examples (it's quite easy to use and fits the borrow checker very well). T

If by "children" you mean self-replicating viral robot swarms, then maybe. Nothing biologically descended from humans will ever leave the heliosphere in any form that could be considered living.

And you wouldn't need to, because the Rust compiler is "slow" relative to compilers like Go. Relative to Clang and g++, the Rust compiler is fast.

By definition, externalizing a cost is less expensive than internalizing it; the only recourse for the rest of us is forcing them to properly internalize their costs.

The point is that urban/rural is irrelevant to this discussion. Every urban area that I've ever lived in has had better air quality than the rural area I grew up in.
