[ident1,ident2,...,DELIM,HMAC,p_header,p_parent,p_content,
buffer1,buffer2,...]
The serialize/unserialize methods convert the nested message dict into this
format.
Parameters
----------
stream : zmq.Socket or ZMQStream
The socket-like object used to send the data.
msg_or_type : str or Message/dict
Normally, msg_or_type will be a msg_type unless a message is being
sent more than once. If a header is supplied, this can be set to
None and the msg_type will be pulled from the header.
content : dict or None
The content of the message (ignored if msg_or_type is a message).
header : dict or None
The header dict for the message (ignores if msg_to_type is a message).
parent : Message or dict or None
The parent or parent header describing the parent of this message
(ignored if msg_or_type is a message).
ident : bytes or list of bytes
The zmq.IDENTITY routing path.
subheader : dict or None
Extra header keys for this message's header (ignored if msg_or_type
is a message).
buffers : list or None
The already-serialized buffers to be appended to the message.
track : bool
Whether to track. Only for use with Sockets, because ZMQStream
objects cannot track messages.
Returns
-------
msg : dict
The constructed message.
(msg,tracker) : (dict, MessageTracker)
if track=True, then a 2-tuple will be returned,

test | deferred | By wrapping a test function with this decorator, you can return a
twisted Deferred and the test will wait for the deferred to be triggered.
The whole test function will run inside the Twisted event loop.
The optional timeout parameter specifies the maximum duration of the test.
The difference with timed() is that timed() will still wait for the test
to end, while deferred() will stop the test when its timeout has expired.
The latter is more desireable when dealing with network tests, because
the result may actually never arrive.
If the callback is triggered, the test has passed.
If the errback is triggered or the timeout expires, the test has failed.
Example::
@deferred(timeout=5.0)
def test_resolve():
return reactor.resolve("www.python.org")
Attention! If you combine this decorator with other decorators (like
"raises"), deferred() must be called *first*!
In other words, this is good::
@raises(DNSLookupError)
@deferred()
def test_error():
return reactor.resolve("xxxjhjhj.biz")

@deferred()

test | Struct.merge | Merge two Structs with customizable conflict resolution.
This is similar to :meth:`update`, but much more flexible. First, a
dict is made from data+key=value pairs. When merging this dict with
the Struct S, the optional dictionary 'conflict' is used to decide
what to do.
If conflict is not given, the default behavior is to preserve any keys
with their current value (the opposite of the :meth:`update` method's
behavior).
Parameters
----------
__loc_data : dict, Struct
The data to merge into self
__conflict_solve : dict
The conflict policy dict. The keys are binary functions used to
resolve the conflict and the values are lists of strings naming
the keys the conflict resolution function applies to. Instead of
a list of strings a space separated string can be used, like
'a b c'.
kw : dict
Additional key, value pairs to merge in
Notes
-----
The `__conflict_solve` dict is a dictionary of binary functions which will be used to
solve key conflicts. Here is an example::
__conflict_solve = dict(
func1=['a','b','c'],
func2=['d','e']
)
In this case, the function :func:`func1` will be used to resolve
keys 'a', 'b' and 'c' and the function :func:`func2` will be used for
keys 'd' and 'e'. This could also be written as::
__conflict_solve = dict(func1='a b c',func2='d e')
These functions will be called for each key they apply to with the
form::
func1(self['a'], other['a'])
The return value is used as the final merged value.
As a convenience, merge() provides five (the most commonly needed)
pre-defined policies: preserve, update, add, add_flip and add_s. The
easiest explanation is their implementation::
preserve = lambda old,new: old
update = lambda old,new: new
add = lambda old,new: old + new
add_flip = lambda old,new: new + old # note change of order!
add_s = lambda old,new: old + ' ' + new # only for str!
You can use those four words (as strings) as keys instead
of defining them as functions, and the merge method will substitute
the appropriate functions for you.
For more complicated conflict resolution policies, you still need to
construct your own functions.
Examples
--------
This show the default policy:
>>> s = Struct(a=10,b=30)
>>> s2 = Struct(a=20,c=40)
>>> s.merge(s2)
>>> sorted(s.items())
[('a', 10), ('b', 30), ('c', 40)]
Now, show how to specify a conflict dict:
>>> s = Struct(a=10,b=30)
>>> s2 = Struct(a=20,b=40)
>>> conflict = {'update':'a','add':'b'}
>>> s.merge(s2,conflict)
>>> sorted(s.items())

You can use those four words (as strings) as keys instead
of defining them as functions, and the merge method will substitute
the appropriate functions for you.
For more complicated conflict resolution policies, you still need to
construct your own functions.
Examples
--------
This show the default policy:
>>> s = Struct(a=10,b=30)
>>> s2 = Struct(a=20,c=40)
>>> s.merge(s2)
>>> sorted(s.items())
[('a', 10), ('b', 30), ('c', 40)]
Now, show how to specify a conflict dict:
>>> s = Struct(a=10,b=30)
>>> s2 = Struct(a=20,b=40)
>>> conflict = {'update':'a','add':'b'}
>>> s.merge(s2,conflict)
>>> sorted(s.items())
[('a', 20), ('b', 70)]

"""Merge two Structs with customizable conflict resolution.
This is similar to :meth:`update`, but much more flexible. First, a
dict is made from data+key=value pairs. When merging this dict with
the Struct S, the optional dictionary 'conflict' is used to decide
what to do.
If conflict is not given, the default behavior is to preserve any keys
with their current value (the opposite of the :meth:`update` method's
behavior).
Parameters
----------
__loc_data : dict, Struct
The data to merge into self
__conflict_solve : dict
The conflict policy dict. The keys are binary functions used to
resolve the conflict and the values are lists of strings naming
the keys the conflict resolution function applies to. Instead of
a list of strings a space separated string can be used, like
'a b c'.
kw : dict
Additional key, value pairs to merge in
Notes
-----
The `__conflict_solve` dict is a dictionary of binary functions which will be used to
solve key conflicts. Here is an example::
__conflict_solve = dict(
func1=['a','b','c'],
func2=['d','e']
)
In this case, the function :func:`func1` will be used to resolve
keys 'a', 'b' and 'c' and the function :func:`func2` will be used for
keys 'd' and 'e'. This could also be written as::
__conflict_solve = dict(func1='a b c',func2='d e')
These functions will be called for each key they apply to with the
form::
func1(self['a'], other['a'])
The return value is used as the final merged value.
As a convenience, merge() provides five (the most commonly needed)
pre-defined policies: preserve, update, add, add_flip and add_s. The
easiest explanation is their implementation::
preserve = lambda old,new: old
update = lambda old,new: new
add = lambda old,new: old + new
add_flip = lambda old,new: new + old # note change of order!
add_s = lambda old,new: old + ' ' + new # only for str!
You can use those four words (as strings) as keys instead
of defining them as functions, and the merge method will substitute
the appropriate functions for you.

construct your own functions.
