示例1: _TagSize
# 需要导入模块: from google.protobuf.internal import wire_format [as 别名]
# 或者: from google.protobuf.internal.wire_format import PackTag [as 别名]
def _TagSize(field_number):
"""Returns the number of bytes required to serialize a tag with this field
number."""
# Just pass in type 0, since the type won't affect the tag+type size.
return _VarintSize(wire_format.PackTag(field_number, 0))
# --------------------------------------------------------------------
# In this section we define some generic sizers. Each of these functions
# takes parameters specific to a particular field type, e.g. int32 or fixed64.
# It returns another function which in turn takes parameters specific to a
# particular field, e.g. the field number and whether it is repeated or packed.
# Look at the next section to see how these are used. 示例2: TagBytes
# 需要导入模块: from google.protobuf.internal import wire_format [as 别名]
# 或者: from google.protobuf.internal.wire_format import PackTag [as 别名]
def TagBytes(field_number, wire_type):
"""Encode the given tag and return the bytes. Only called at startup."""
return six.binary_type(
_VarintBytes(wire_format.PackTag(field_number, wire_type)))
# --------------------------------------------------------------------
# As with sizers (see above), we have a number of common encoder
# implementations. 示例3: testPackTag
