Struct PyECParameters 

pub struct PyECParameters { /* private fields */ }

EC domain parameters (RFC 3279 §2.3.5, X9.62).

A CHOICE with three alternatives:

• namedCurve — an OID identifying a well-known curve (most common in X.509)
• ecParameters — explicit SpecifiedECDomain (rarely used in PKI)
• implicitlyCA — NULL (inherit parameters from the CA certificate)

Use :attr:arm to determine which alternative is present, and :attr:named_curve_oid to obtain the OID for the namedCurve arm.

import synta.pkixalgs as pa
params = pa.ECParameters.from_der(alg_params_der)
if params.arm == "namedCurve":
    print(params.named_curve_oid)

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<PyECParameters>

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.
