Introduction
Rust, known for its safety and performance, is not without its challenges, particularly in debugging. In February 2026, the first Rust Debugging Survey was launched to better understand how developers use debugging tools and the challenges they face. With over 2,300 responses, this survey provides valuable insights into current practices and hurdles to overcome.
Who Uses Debuggers?
The survey reveals that over 80% of respondents consider themselves "Advanced" or "Intermediate" Rust users. However, more than half do not currently use a debugger for Rust. Among "beginners," about 50% have never used debuggers, whereas nearly half of "advanced users" currently do. This highlights a disparity in the adoption of debugging tools, possibly linked to perceived complexity or a lack of suitable resources for beginners.
How Are Debuggers Used?
Rust developers largely favor print debugging and the use of the dbg! macro. Beyond these methods, lldb within an IDE and gdb on the command line are the most popular choices. On Linux systems, gdb on the command line is particularly favored. These preferences indicate a reliance on traditional methods, which might suggest frustration with integrated debugging tools or unfamiliarity.
Challenges Faced
The main complaints often concern the complexity and lack of documentation of debuggers for Rust. For 3% of users who stopped using Rust, debugging issues were a decisive factor. Additionally, 24% cited these issues as one of the reasons for quitting. Although modest, these figures point to a crucial need for improvements in debugging tools to retain and attract more developers.
Debugger Visualizers
Debugger visualizers also play an essential role. Respondents expressed interest in more intuitive tools that simplify understanding large data structures and complex execution flows. Developing these tools could transform the debugging experience for Rust users.
Conclusion
The 2026 Rust Debugging Survey highlights significant but surmountable challenges. With better documentation, more robust tools, and increased attention to beginner needs, Rust could not only improve its debugging experience but also expand its developer community.
