rython-calc 0.4.13

Small project developed by me to learn PyO3 library.

Rython

Use text_signature to create python type

/// Formats the sum of two numbers as string.
#[pyfunction(text_signature = "(a: int, b: int) -> str")]
fn sum_as_string(a: usize, b: usize) -> PyResult<String> {
    Ok((a + b).to_string())
}

Add .pyi file using mypy

Keep in mind that is only works for #[pyfunction]. Macros like #[pyclass] and #[pymethods] are still unsupported.

For autocompletion .pyi in bash type:

stubgen -p rython.calc -o python

It will produce calc.pyi with:

def sum_as_string(a: int, b: int) -> str: ...
