Crate pyo3_error

Unified error causality chains across Rust and Python using PyErrChain.

Structs

• DowncastToPyErr
  Try to map a std::error::Error via a specific error type T to a PyErr by downcasting when used as MapErrorToPyErr;
• ErrorNoPyErr
  Never attempt to translate any std::error::Error to PyErr when used as AnyErrorToPyErr.
• IoErrorToPyErr
  Translate std::io::Error to PyErr when used as AnyErrorToPyErr.
• PyErrChain
  PyErrChain wraps a PyErr together with its causality chain.

Traits

• AnyErrorToPyErr
  Utility trait to try to translate from std::error::Error to PyErr.
• MapErrorToPyErr
  Utility trait to try to translate via specific error types E implementing std::error::Error and wrapped errors such as MyError<E> to PyErrs.

Functions

• err_with_location
  Utility function to add a traceback with the error’s file, line, and column location information to the err.
