Description

Is there any standard way to detect if the code is running with the rust analyzer or not?

I'd like to be able to compile parts of my proc macro only in actual builds and not when the rust analyzer is running it.

Research direction

No files or tests are named. Start by investigating how rust-analyzer runs proc macros and what environment or configuration differs from an actual build; determine whether a standard detection mechanism exists. Done means a reliable way to distinguish rust-analyzer execution from actual builds, with the behavior documented or supported.
