Based on Google’s internal experiences with using Rust, they shared their insights on this “popular” programming language, including clarifications on common Rust myths.
1. Rust Requires At Least 6 Months to Learn
Google refuted this claim.
According to an internal survey, over 2/3 of respondents felt confident that they could contribute to the Rust codebase within two months or less. Additionally, 1/3 of respondents became as efficient with Rust in two months or less as they were with other languages. This figure increased to over 50% within four months.
2. Rust Compiler Speed Is Not As Fast As Imagined
Google confirmed this statement.
They stated that, so far, slow build speed is the biggest challenge developers face when using Rust, with only slightly more than 40% of respondents finding the speed acceptable.
3. Unsafe Code and Interoperability Are Always the Biggest Challenges
Google refuted this claim.
For current Google developers, the three major challenges they face in the Rust domain are:
-
Macros
-
Ownership and Borrowing
-
Async Programming
Writing unsafe code and handling C/C++ interoperability are also issues encountered by Google developers, but they are not the biggest challenges.
4. Rust’s Compiler Error Messages Are Very Helpful
Google confirmed this statement.
Only 9% of respondents in Google’s internal survey were dissatisfied with the quality of diagnostic and debugging information in Rust.
Feedback from the community has shown that many are impressed by the compiler messages’ performance. Although initially surprised—after all, people are used to ignoring large compiler errors—once accustomed, they grew to like it.
5. Rust’s Code Quality Is High
Respondents indicated that the quality of Rust code is high—77% of developers are satisfied with the quality of Rust code. In fact, when asked to compare whether they believe Rust code is more correct than code written in other languages, a vast majority (85%) believe their Rust code is correct.
Besides correctness, Rust code is also easy to review, with over half of respondents stating that Rust code is very easy to review.
