Module runtime 

Runtime support for type aliases.

This module provides traits and utilities for registering type aliases in Python modules at runtime, enabling type aliases defined with type_alias! to be importable from Python.

Example

use pyo3::prelude::*;
use pyo3_stub_gen::type_alias;
use pyo3_stub_gen::runtime::PyModuleTypeAliasExt;

// Define a runtime type alias
type_alias!("my_module", NumberOrString = i32 | String);

#[pymodule]
fn my_module(m: &Bound<PyModule>) -> PyResult<()> {
    // Register the type alias at runtime
    m.add_type_alias::<NumberOrString>()?;
    Ok(())
}

Traits

PyModuleTypeAliasExt

Extension trait for Bound<PyModule> to add type aliases.

PyRuntimeType

Trait for Rust types that can be converted to Python type objects at runtime.

PyTypeAlias

Trait for type aliases that can be registered at runtime.

Functions

union_type

Creates a Python union type using the | operator (Python 3.10+).
