Wrong Python imports needed depending on pyproject.toml location

[cocool97]

Bug Description

Hi,

I'm using you project to build a Python package for my library adb_client. I'm facing an issue I haven't find any workaround.

Project structure:

Cargo.toml
lib1
|----------- Cargo.toml
lib2
|----------- Cargo.toml
python_lib
|----------- Cargo.toml

I want to include files from lib2 inside my wheel to let people build the crate if needed.

• If I put my pyproject.toml at the root of my workspace, the build process is fine, but I need from python_lib import python_lib when using the Python library.

• If I put my pyproject.toml inside python_lib directory, imports are good for me from python_lib import Class1, Class2 but I can't embed source code from lib2 (seems to be chrooted at pyproject.toml location.

My goal is to be able to from python_lib import Class1, Class2 for practical reasons.

My pyproject.toml is the following when located at the root directory:

[tool.maturin]
include = [{ path = "lib2/**/*", format = "sdist" }]
features = ["pyo3/extension-module"]
manifest-path = "python_lib/Cargo.toml"

Is there something I'm doing wrong ?

Thanks !

Your maturin version (maturin --version)

maturin 1.8.1

Your Python version (python -V)

Python 3.13.1

Your pip version (pip -V)

pip 24.2

What bindings you're using

pyo3

Does cargo build work?

• Yes, it works

If on windows, have you checked that you aren't accidentally using unix path (those with the forward slash /)?

• Yes

Steps to Reproduce

1. pyproject.toml at the root

2. maturin build --release

3. => Check that imports are from python_lib import python_lib

4. pyproject.toml inside python_lib

5. maturin build --release

6. => Check that imports are from python_lib import Class1, Class2, but files from lib2 aren't included

You don't need to embed source code from lib2 if it's a crates.io dependency, but if you want to embed it then it should be configured as a cargo path dependency.

Thanks, indeed embedding files is not mandatory, this fixes my issue :)
