Rust developers have three big worries – survey

The other biggest worries were that Rust may become too complex (41.6% in 2025 versus 45.2% in 2024) and that the developers and maintainers of Rust are not properly supported (38.4% in 2025 versus 35.4% in 2024). The survey also asked developers which aspects of Rust present non-trivial problems to their programming productivity. Here slow compilation led the way, with 27.9% of developers saying slow compilation was a big problem and 54.68% saying that compilation could be improved but did not limit them. High disk space usage and a subpar debugging experience were also top complaints, with 22.24% and 19.90% of developers citing them as big problems. … - 91.7% of respondents reported using Rust in 2025, down from 92.5% in 2024. ... - Generic const expressions was the leading unimplemented or nightly-only feature that respondents in 2025 were looking to see stabilized, with 18.35% saying the feature would unblock their use case and 41.53% saying it would improve their code.
