Debugging Rust apps with GDB

Debugging is an essential aspect of software development that varies significantly across different programming ecosystems. In languages like Java, with its rich tooling, debuggers are integral to the workflow, whereas in dynamically typed languages, this practice might not be as prevalent. This tutorial focuses on debugging Rust applications using the GNU Project Debugger (GDB), a versatile tool that supports multiple languages, including Rust. The guide outlines setting up a Rust project with GDB, emphasizing the use of rust-gdb, a wrapper enhancing GDB with pretty-printing for Rust data types. Through examples, it demonstrates basic debugging operations like setting breakpoints, inspecting variables, and handling asynchronous network applications using the Tokio async runtime. While GDB provides strong foundational debugging capabilities, especially with rust-gdb's enhancements, more sophisticated debugging features seen in other languages' GUI debuggers are still under development for Rust.
