What's the reason for this assertion? Can we not just do nid = pkcs7.type_().map(|t| t.nid()); if nid != Some(PKCS7_SIGNED) {}?

I replicated the behavior from the Python implementation: src. Should I change it?

Yes, I think my formulation here is better --
it's important to note that the openssl_assert() would produce a python execption while this code would produce a rust panic, so they're not quite teh same

Round-trip via DER, it'll be faster.

Leaving as a draft for now since |

I believe that's because BoringSSL is missing PKCS#7 functionality -- we should just disable this there. |

Use UNSUPPORTED_SERIALIZATION here I think

Small nit: Instead of returning a Vec, I'd suggest the &pyo3::types::PyList. This avoids a copy+malloc round trip.
See verify.rs l239 for an example of this

You're getting coverage issues here. Best resolution is to rewrite as:
let cert_der = pyo3::types::PyBytes::new(py, c.to_der()?.as_slice()).into_py(py);
let cert = load_der_x509_certificate(py, cert_der, None)?;
result.append(cert.into_py(py))?;

Part of #8770. Now that
rust-opensslhas the necessary bindings, this PR replaces the Python implementation with calls to the Rust OpenSSL bindings.
