Struct PyHmacDigest 

pub struct PyHmacDigest { /* private fields */ }

Incremental HMAC computation.

Feed data in chunks with :meth:update, then call :meth:finalize to obtain the MAC bytes. The object is consumed by :meth:finalize and cannot be reused.

import synta

h = synta.HmacDigest("sha256", b"secret-key")
h.update(b"chunk 1")
h.update(b"chunk 2")
mac = h.finalize()

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<PyHmacDigest>

This handles following two situations:

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

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.
