Stepping into the Rust Std library

Stepping into is_digit from the standard library

If you wish to step into the Rust standard library code (and some do for curiosity or to help debug a deeper problem) you can do this with sourceFileMap. With CodeLLDB you could use a wildcard (/rustc/*) but that feature has since broke, see tracking issues at the bottom.

On the C/C++ extension this isn’t possible without updating the string each time you update your toolchain. This is because the long string you see after /rustc/[here] depends on the exact toolchain you have installed, so every time you update the toolchain this string will change.

You can find out the string by stepping into a native function and copying the “source location”. It will look something like this:
