Section titled “tl_fast_decode”fn tl_fast_decode(py: Python<'_>, constructor_id: u32, data: &[u8], offset: usize, boxed: bool) -> PyResult<Option<(Py<pyo3::types::PyTuple>, usize)>>Defined in rust/miniproto/src/tl.rs:210-266
Attempts Python tl_fast_decode for a generated constructor at offset.
boxed requires and verifies the constructor id. Returns None if no native decoder exists,
otherwise (values_tuple, next_offset); malformed wire input raises a Python exception. This
conversion necessarily holds the GIL to create Python objects. PyO3 conversion errors are
propagated unchanged, whereas malformed TL bytes use ValueError. Descriptor indices and flag
bits come from trusted generated metadata and are not revalidated on every hot-path call.
