Function mentat_ffi::utils::error::translate_result

pub unsafe fn translate_result<T, E>(
    result: Result<T, E>, 
    error: *mut ExternError
) -> *mut T where
    E: Display, 

Translate Result<T, E>, into something C can understand, when T is not #[repr(C)]

• If result is Ok(v), moves v to the heap and returns a pointer to it, and sets error to a state indicating that no error occurred (message is null).
• If result is Err(e), returns a null pointer and stores a string representing the error message (which was allocated on the heap and should eventually be freed) into error.message
