How to configure codelldb to debug Substrate/Rust code?

[rlaferla]

I can get codelldb to debug the client node (Rust) code but I want to set breakpoints in the Substrate library (different source directory). I don't understand what the correct value is for the "from" mapping. I think the "to" mapping is to the root of the Substrate source directory.

"sourceMap": { "???" : "../../paritytech/substrate/substrate" }

I am not familiar with Substrate or its build system.
In general, you need to reconcile the view of the file system as the compiler saw it, and as the editor (VSCode) currently sees it. For local builds these are the same, but if build happens on a remote server or in a container, you will need to provide the mapping in the form { "<where compiler saw source code>" : "<where the editor sees it now>". Note, that for build reproducibility, some build systems intentionally replace the compile-time path with a constant string (such as "/proc/self/cwd").
