also just want to mention

rust and its bastard children do have garbage collectors

the biggest difference (aside from OOP data model) between #golang and #rust is that rust forces the programmer to explicitly state where a variable is in scope, the so-called "escape" problem

Go's GC uses a heuristic to try and (conservatively) pick memory allocations that are stale or definitely not in scope whereas Rust forces the programmer to stipulate when a variable is in scope

this lets Rust apps squeeze a little more performance, in the same way as C++, at the expense of high complexity of compilation (read memory and time cost for developers) and a longer test/edit cycle (because of that)

the margin is no more than about 5%

it's not worth it when you consider that it doesn't actually matter that much, 5% better performance, when it costs $5/month for the basic VPS and that means 10 cents saving versus if you wrote your shit in Go, which saves you 5% on the cost of your programmers
