Python.Inline.Literal

Conversion between haskell data types and python values

Documentation

class FromPy a where

Convert python object to haskell value.

Methods

basicFromPy :: Ptr PyObject -> Py a

Convert python value into haskell value. This function should try to not modify python's data. This function should avoid throwing haskell exception. Any python exceptions should be thrown as PyError. When data type couldn't be converted BadPyType or OutOfRange should be thrown to indicate failure.

This is low level function. It should be only used when working with python's C API. Otherwise fromPy is preferred.

class ToPy a where

Convert haskell value to python value.

Minimal complete definition

basicToPy

Methods

basicToPy :: a -> Py (Ptr PyObject)

Convert haskell value to python object. This function returns strong reference to newly create objects (except singletons like None, True, etc).

Implementations should try to avoid failing conversions. There're two ways of signalling failure: errors on python side should return NULL and raise python exception. Haskell code should just throw exception.

This is low level function. It should be only used when working with python's C API. Otherwise toPy is preferred.
