Stefan Filip 7f72a04c0e metrics: crate for collecting metrics 
Summary:
We start off simple here. Python only really has counters so we only implement
counters. There are a lot of options on how to improve this and things get
slightly complicated when we look at the how ecosystem and fb303. Anyway,
simple start.

README.md

lib

Any native code (C/C++/Rust) that Mercurial (either core or extensions) depends on should go here. Python code, or native code that depends on Python code (e.g. #include <Python.h> or use cpython) is disallowed.

As we start to convert more of Mercurial into Rust, and write new paths entrirely in native code, we'll want to limit our dependency on Python, which is why this barrier exists.

See also hgext/extlib/README.md, mercurial/cext/README.mb.

How do I choose between lib and extlib (and cext)?

If your code is native and doesn't depend on Python (awesome!), it goes here.

Otherwise, put it in hgext/extlib (if it's only used by extensions) or mercurial/cext (if it's used by extensions or core).
