Trait for types which can represent a Python mapping

Required Associated Types

type Builder

Builder type for Python mappings

Required Methods

fn builder(py: Python<'py>, len: Option<usize>) -> PyResult<Self::Builder>

Create a builder for a Python mapping

fn push_item( builder: &mut Self::Builder, key: Bound<'py, PyAny>, value: Bound<'py, PyAny>, ) -> PyResult<()>

Adds the key-value item to the mapping being built

fn finish(builder: Self::Builder) -> PyResult<Bound<'py, PyMapping>>

Build the Python mapping

Object Safety

This trait is not object safe.
