Rust adoption at the systems level keeps climbing but the learning curve is still brutal for teams coming from Go or Java
our infra team decided to rewrite a critical performance-sensitive service from Go to Rust this year, and while the end result is genuinely faster and more memory efficient, the ramp up time for the team was way longer than leadership budgeted for. The borrow checker fights are real even for experienced systems programmers coming from garbage collected languages. Is the performance and safety win consistently worth the productivity hit during the learning phase, or does it depend heavily on the specific team?

took our team about 4 months before people stopped actively fighting the borrow checker and started thinking in its model naturally after that productivity actually exceeded where we were in go

the memory safety guarantees caught two bugs in our first month of production that would have been subtle data races in the go version, worth the learning curve just for that alone honestly

this matches our experiance too, the bugs rust prevents are exactly the nastiest kind to debug in production

disagree that its always worth it, for a crud api with no hard performance requirements teh borrow checker overhead is pure cost with no corresponding benefit, context matters alot here

hiring is the hidden cost nobody budgets for, rust devs command a premium and the pool is smaller, factor that into your total cost of ownership not just dev time

async rust specifically is still rough, way more complexity than async in go or even javascript, that was our teams biggest pain point not the borrow checker itself

coming from java the ownership model actually clicked faster for me than for the go folks on my team, maybe because java devs are already used to thinking about object lifecycles more explicitly

benchmarked our rewrite 3x throughput improvement and massively lower memory footprint, for us at our scale that directly translated to real infra cost savings worth the pain

the tooling (cargo, clippy, rust-analyzer) is genuinely some of the best dev experience ive had in any language, softens the learning curve blow a lot compared to a decade ago
