Struct PyAlgorithmIdentifier 

pub struct PyAlgorithmIdentifier { /* private fields */ }

An X.509 AlgorithmIdentifier SEQUENCE (RFC 5280 §4.1.1.2).

Wraps an algorithm OID and optional parameters as a pre-encoded DER SEQUENCE. Use :meth:to_der to obtain bytes ready for passing to builder APIs such as :meth:~synta.CertificateListBuilder.signature_algorithm.

Two constructors handle the two conventions used in practice:

• :meth:from_oid — RSA-family algorithms; encodes SEQUENCE { oid, NULL }
• :meth:from_oid_no_params — ECDSA/EdDSA; encodes SEQUENCE { oid }

import synta
alg = synta.AlgorithmIdentifier.from_oid(synta.oids.SHA256_WITH_RSA)
crl_builder.signature_algorithm(alg.to_der())

Docstring for the class provided on the struct or enum.

const DOC: &'static CStr

Fully rendered class doc, including the text_signature if a constructor is defined.

type BaseType = PyAny

Base class

type ThreadChecker = SendablePyClass<PyAlgorithmIdentifier>

This handles following two situations:

type PyClassMutability = <<PyAny as PyClassBaseType>::PyClassMutability as PyClassMutability>::ImmutableChild

Immutable or mutable

type Dict = PyClassDummySlot

Specify this class has #[pyclass(dict)] or not.

type WeakRef = PyClassDummySlot

Specify this class has #[pyclass(weakref)] or not.

type BaseNativeType = PyAny

The closest native ancestor. This is PyAny by default, and when you declare #[pyclass(extends=PyDict)], it’s PyDict.
