How to add private methods to pyo3 pymethods?

问题

  1. #[pyclass]
  2. pub struct SomeItem;
  4. #[pymethods]
  5. impl SomeItem {
  6.     #[new]
  7.     pub fn new() -> Self {  // visible for python constructor
  8.         SomeItem;
  9.     }
  11.     pub fn method(&self) -> u8 {  // visible for python method
  12.         self.hidden_method()
  13.     }
  15.     #[pyo3(ignore)]  // just for example
  16.     fn hidden_method(&self) -> u8 {  // invisible for python method (that must be able to return non-python type)
  17.         0
  18.     }
  19. }

I'd like to add hidden methods to pyo3 class methods implementation which will be invisible for Python.

Example:

  1. #[pyclass]
  2. pub struct SomeItem;
  4. #[pymethods]
  5. impl SomeItem {
  6.     #[new]
  7.     pub fn new() -> Self {  // visible for python constructor
  8.         SomeItem;
  9.     }
  11.     pub fn method(&self) -> u8 {  // visible for python method
  12.         self.hidden_method()
  13.     }
  15.     #[pyo3(ignore)]  // just for example
  16.     fn hidden_method(&self) -> u8 {  // invisible for python method (that must be able to return non-python type)
  17.         0
  18.     }
  19. }

关于使用单独的 impl 块呢？

  1. #[pymethods]
  2. impl SomeItem {
  3.     #[new]
  4.     pub fn new() -> Self {  // 对Python构造函数可见
  5.         SomeItem;
  6.     }
  8.     pub fn method(&self) -> u8 {  // 对Python方法可见
  9.         self.hidden_method()
  10.     }
  11. }
  13. impl SomeItem {
  14.     fn hidden_method(&self) -> u8 {
  15.         0
  16.     }
  17. }
英文:

What about using a separate impl block?

  1. #[pymethods]
  2. impl SomeItem {
  3.     #[new]
  4.     pub fn new() -> Self {  // visible for python constructor
  5.         SomeItem;
  6.     }
  8.     pub fn method(&self) -> u8 {  // visible for python method
  9.         self.hidden_method()
  10.     }
  11. }
  13. impl SomeItem {
  14.     fn hidden_method(&self) -> u8 {
  15.         0
  16.     }
  17. }
