Trait PyModuleTypeAliasExt 

pub trait PyModuleTypeAliasExt {
    // Required method
    fn add_type_alias<T: PyTypeAlias>(&self) -> PyResult<()>;
}

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

This trait provides a convenient method for registering type aliases in Python modules.

Example

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

#[pymodule]
fn my_module(m: &Bound<PyModule>) -> PyResult<()> {
    m.add_type_alias::<MyTypeAlias>()?;
    Ok(())
}

Required Methods

fn add_type_alias<T: PyTypeAlias>(&self) -> PyResult<()>

Adds a type alias to this module.

The type alias will be available as a module attribute with the name specified by T::NAME.

Type Parameters

• T - A type implementing PyTypeAlias

Errors

Returns an error if:

• Creating the type object fails
• Adding the attribute to the module fails

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
