crates/native_blockifier/src/py_utils.rs line 15 at r1 (raw file):

#[derive(Clone, Copy, Default, Eq, FromPyObject, Hash, PartialEq, Debug, Serialize)]
pub struct PyFelt(#[pyo3(from_py_with = "int_to_stark_felt")] pub StarkFelt);

Does this mean that it already knows to map it into an int on serialize?

Code quote:

#[derive(Clone, Copy, Default, Eq, FromPyObject, Hash, PartialEq, Debug, Serialize)]
pub struct PyFelt(#[pyo3(from_py_with = "int_to_stark_felt")] pub StarkFelt);

Good.
While this is being tested, if you want @elintul, we can check if this can be done solely with derive serde::Serialize in those structs + some serde customizations for specific serialization logic, i believe it can.

Also, you can consult with DanB team, they do stuff like this efficiently.

Is this PR still relevant given your other PR that uses Serialize?

I will close this PR., as we've decide to change the Python class instead.
