Based on early data I’m seeing from @RareCodeAI it takes about 20-30 hours of dedicated Rust practice to get to the point of “mastering” Rust. By “mastering” Rust I mean: - You can whip up a solution to a common problem (let’s say find strings in a set that are anagrams of each other) without straining yourself. - You can sense what syntax is available to you in an unfamiliar situation. - Most compiler errors don’t scare you and you can immediately recognize the solution to the most common ones. This 20-30 hours does NOT include: - reading tutorials - spending time figuring out what to practice and review - deciding if you should learn something new or practice something from earlier Without RareCode, I suspect the time required would be closer to 40 to 80 hours. So before you force devs to learn Rust to use your product, consider the fact that most people don’t want to go through 80 grueling hours.
