Macro rigetti_pyo3::py_wrap_error

macro_rules! py_wrap_error {
    ($module: ident, $rust: ty, $python: ident, $base: ty) => { ... };
}

Creates a new exception type and implements converting from the given Rust error to the new exception.

The Rust error type must at least implement ToString. All types that implement Error implement this through Display.
