Rust analyzer: analyze file from other extension

I wanted to know if it is possible for rust analyzer to add a breakpoint in another file extension, not a .rs one.
My goal is to create a macro which will load rust code from inside another file extension .md.
For now, I can place some breakpoints inside my macro without any problem and debugging works as expected.
But it would be great if I could load the file from my macro and place breakpoints inside this other file extension to accomplish the same task.

Any idea ?

Thank you in advance for your help.

It's not my understanding that RA assesses variables at anything other than the level of types.
