--> tests/ui/invalid_result_conversion.rs:21:1
|
21 | #[pyfunction]
| ^^^^^^^^^^^^^ the trait `From<MyError>` is not implemented for `PyErr`

= help: the following other types implement trait `From<T>`:
<PyErr as From<std::io::Error>>
<PyErr as From<PyBorrowError>>
<PyErr as From<PyBorrowMutError>>
<PyErr as From<PyDowncastError<'a>>>
<PyErr as From<DowncastError<'_, '_>>>
<PyErr as From<DowncastIntoError<'_>>>
<PyErr as From<NulError>>
<PyErr as From<IntoStringError>>
and $N others
= note: required for `MyError` to implement `Into<PyErr>`
= note: this error originates in the attribute macro `pyfunction` (in Nightly builds, run with -Z macro-backtrace for more info)
