Class PyLlmCodecWrapper

crates/python/src/py_callable.rs:883–885

Wraps a Python object with ``decode``/``encode`` methods into the Rust [`LlmCodec`] trait so it can be stored in the global codec registry. The Python codec object must implement: - ``decode(request: LlmRequest) -> AnnotatedLLMRequest`` - ``encode(annotated: AnnotatedLLMRequest, original: LlmRequest) -> LlmRequest``

/// - ``decode(request: LlmRequest) -> AnnotatedLLMRequest``
/// - ``encode(annotated: AnnotatedLLMRequest, original: LlmRequest) -> LlmRequest``
pub(crate) struct PyLlmCodecWrapper {
    pub py_codec: Py<PyAny>,
}

// SAFETY: The Py<PyAny> handle is GIL-independent (ref-counted via Python's
// allocator). All access goes through `Python::attach` which acquires the GIL.
