示例1: _TagSize
# 需要導入模塊: from google.protobuf.internal import wire_format [as 別名]
# 或者: from google.protobuf.internal.wire_format import PackTag [as 別名]
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.

# --------------------------------------------------------------------
# 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
# 需要導入模塊: from google.protobuf.internal import wire_format [as 別名]
# 或者: from google.protobuf.internal.wire_format import PackTag [as 別名]
