VSCode Debugger won't stop at breakpoints in Rust code

Question

I am learning Rust through the rustlings project, and I cannot get VSCode to stop at my breakpoints no matter what tutorial I follow on Rust debugging. I am currently doing this on Mac OS 12.6.

I installed rust-analyzer installed, and CodeLLDB , and set “allow breakpoints anywhere” to enabled.

The file I am trying to debug is intro2.rs. I tried compiling it a couple of times by running rustc .../rustlings/intro/intro2.rs, and an executable (I think) file intro2 appears in the intro folder. Then I tried running the debugger but it doesn't stop at my breakpoints, and it doesn't output the print statements in my code (I do get the messages if I run executable directly from the command line).

I tried building the whole rustlings project by running "cargo build" in the rustlings directory and I get a message saying: "Finished dev [unoptimized + debuginfo] target(s) in 0.09s" and a file called rustlings appears in the directory ".../rustlings/target/debug". Still the debugger won't stop at my breakpoints.

I have my launch.json file set up as shown below at the end with the "program" property set to either one of: "program": /path/to/intro2 OR "program": .../rustlings/target/debug/rustlings

still nothing.

The debugger does stop at some assembly instructions if I add "main" to my breakpoints which leads me to conclude that the debugger is working but the debug info is not included when compiling "intro2.rs" but I don't why that's the case.

Someone please help!
