Is it possible to use a manifest-path to a file not named "Cargo.toml"

[AmitPr]

Hi,
I'm working on a project that needs bindings both for python and for WASM. Because of this, I believe the easiest way to have the two different build systems work is to have two Cargo.toml files, one for bindings using PyO3 (py_Cargo.toml) and one using wasm-pack(wasm_Cargo.toml).

I was wondering whether it's possible then, to have maturin use this py_Cargo.toml file instead of looking for a Cargo.toml. I've tried:

maturin develop -m py_Cargo.toml 
    💥 maturin failed
      Caused by: Cargo metadata failed. Does your crate compile with `cargo build`?
      Caused by: `cargo metadata` exited with an error: error: the manifest-path must be a path to a Cargo.toml file

Am I missing something?

Can you make cargo build --manifest-path py_Cargo.toml work? (AFAIK it's not working) If not maturin also can't do it.

I encourage you to comment on the upstream cargo issue so it may get fixed someday.

I see, not super familiar with rust yet :)
Thanks for the info!
