Unless the environment is also touched by a part of the program written in Go, Julia, I don't know... The lock is not shared across languages.

Which just to be clear: it cannot without changing the standard. There is really nothing anyone can do without a change in the standard.

However, to access any of those languages from rust you need to use unsafe.

[eptcyka]

There is no safe way to access the environment, even if you mark this API unsafe, what are you going to do?

[bbatha]

You can safely access the environment so long as you use the rust apis and don't have unsafe code that calls `setenv` without synchronization.
