How do I use GDB with Rust?

To use GDB with Rust, first ensure you have the Rust toolchain installed. You can compile your Rust code with debugging information using the command cargo build --debug. Then, you can start GDB with your compiled binary using gdb target/debug/your_binary_name.

What are some common GDB commands I should know?

Some common GDB commands include:

1. run - to start your program.
2. break <line_number> - to set a breakpoint.
3. next - to execute the next line of code.
4. print <variable> - to inspect the value of a variable.
5. continue - to resume execution until the next breakpoint.

Can I use GDB with Rust's async features?

Yes, you can use GDB with Rust's async features. However, debugging async code can be more complex due to the nature of futures and tasks. You may need to set breakpoints in specific async functions and understand how the state is managed across await points.

Are there any GUI tools for GDB?

Yes, there are several GUI front-ends for GDB, such as GDB Dashboard, DDD, and Eclipse with the CDT plugin. These tools can make it easier to visualize your debugging sessions.
