Function pre_initialize 

pub async fn pre_initialize(
    python_stdlib: &Path,
    site_packages: Option<&Path>,
    imports: &[&str],
    extensions: &[NativeExtension],
) -> Result<Vec<u8>>

Available on crate feature preinit only.

Pre-initialize a Python component with native extensions.

This function links the component with native extensions, runs the Python interpreter’s initialization, optionally imports modules, and captures the initialized memory state into the returned component.

Arguments

• python_stdlib - Path to Python standard library directory
• site_packages - Optional path to site-packages directory
• imports - Modules to import during pre-init (e.g., [“numpy”, “pandas”])
• extensions - Native extensions to link into the component

Returns

The pre-initialized component bytes, ready for instantiation.

Errors

Returns an error if pre-initialization fails (e.g., Python init error, import failure).
