Macro gen_methods_from_python

gen_methods_from_python!() { /* proc-macro */ }

Generate PyMethodsInfo from Python class definition

This proc-macro parses Python class definition syntax and generates a PyMethodsInfo structure. It should be used inside inventory::submit! blocks.

Supports single or multiple method definitions within a class:

// Single method
submit! {
    gen_methods_from_python! {
        r#"
        class Incrementer:
            def increment_1(self, x: int) -> int:
                """Increment by one"""
        "#
    }
}

// Multiple methods
submit! {
    gen_methods_from_python! {
        r#"
        class Incrementer2:
            def increment_2(self, x: float) -> float:
                """Increment by two (float version)"""

            def __new__(cls) -> Incrementer2:
                """Constructor"""

            def increment_2(self, x: int) -> int:
                """Increment by two (int version)"""
        "#
    }
}
