cdef class Unpacker(object):
"""Streaming unpacker.
"""
MessagePack Packer
Arguments:
Usage::
:param file_like:
File-like object having `.read(n)` method.
If specified, unpacker reads serialized data from it and :meth:`feed()` is not usable.
packer = Packer()
astream.write(packer.pack(a))
astream.write(packer.pack(b))
:param int read_size:
Used as `file_like.read(read_size)`. (default: `min(1024**2, max_buffer_size)`)
Packer's constructor has some keyword arguments:
:param bool use_list:
If true, unpack msgpack array to Python list.
Otherwise, unpack to Python tuple. (default: True)
:param callable default:
Convert user type to builtin type that Packer supports.
See also simplejson's document.
:param bool raw:
If true, unpack msgpack raw to Python bytes.
Otherwise, unpack to Python str by decoding with UTF-8 encoding (default).
:param bool use_single_float:
Use single precision float type for float. (default: False)
:param bool strict_map_key:
If true (default), only str or bytes are accepted for map (dict) keys.
:param bool autoreset:
Reset buffer after each pack and return its content as `bytes`. (default: True).
If set this to false, use `bytes()` to get content and `.reset()` to clear buffer.
:param callable object_hook:
When specified, it should be callable.
Unpacker calls it with a dict argument after unpacking msgpack map.
(See also simplejson)
:param bool use_bin_type:
Use bin type introduced in msgpack spec 2.0 for bytes.
It also enables str8 type for unicode. (default: True)
:param callable object_pairs_hook:
When specified, it should be callable.
Unpacker calls it with a list of key-value pairs after unpacking msgpack map.
(See also simplejson)
:param bool strict_types:
If set to true, types will be checked to be exact. Derived classes
from serializable types will not be serialized and will be
treated as unsupported type and forwarded to default.
Additionally tuples will not be serialized as lists.
This is useful when trying to implement accurate serialization
for python types.
:param int max_buffer_size:
Limits size of data waiting unpacked. 0 means system's INT_MAX.
The default value is 100*1024*1024 (100MiB).
Raises `BufferFull` exception when it is insufficient.
You should set this parameter when unpacking data from untrusted source.
:param int max_str_len:
Deprecated, use *max_buffer_size* instead.
Limits max length of str. (default: max_buffer_size)
:param int max_bin_len:
Deprecated, use *max_buffer_size* instead.
Limits max length of bin. (default: max_buffer_size)
:param int max_array_len:
Limits max length of array. (default: max_buffer_size)
:param int max_map_len:
Limits max length of map. (default: max_buffer_size//2)
:param int max_ext_len:
Deprecated, use *max_buffer_size* instead.
Limits max size of ext type. (default: max_buffer_size)
:param bool datetime:
If set to true, datetime with tzinfo is packed into Timestamp type.
Note that the tzinfo is stripped in the timestamp.
You can get UTC datetime with `timestamp=3` option of the Unpacker.
(Python 2 is not supported).
:param str unicode_errors:
Error handler used for decoding str type. (default: `'strict'`)
The error handler for encoding unicode. (default: 'strict')
DO NOT USE THIS!! This option is kept for very specific usage.
