Interface FromPyObject

src/conversion.rs:102–105

FromPyObject is implemented by various types that can be extracted from a Python object. Normal usage is through the `PyObject::extract` helper method: ```let obj: PyObject = ...; let value = obj.extract:: (py)?; ``` Each target type for this conversion supports a different Python objects as input. Calls with an unsupported input object will result in an exception (usually a `TypeErro

/// When these macros are used with reference parameters (`x: &str`), the trait
/// `RefFromPyObject` is used instead.
pub trait FromPyObject<'s>: Sized {
    /// Extracts `Self` from the source `PyObject`.
    fn extract(py: Python, obj: &'s PyObject) -> PyResult<Self>;
