Contains the logic for encoding every logical protocol field type
into one of the 5 physical wire types.
This code is designed to push the Python interpreter's performance to the
limits.
The basic idea is that at startup time, for every field (i.e. every
FieldDescriptor) we construct two functions: a "sizer" and an "encoder". The
sizer takes a value of this field's type and computes its byte size. The
encoder takes a writer function and a value. It encodes the value into byte
strings and invokes the writer function to write those strings. Typically the
writer function is the write() method of a BytesIO.
We try to do as much work as possible when constructing the writer and the
sizer rather than when calling them. In particular:
* We copy any needed global functions to local variables, so that we do not need
to do costly global table lookups at runtime.
* Similarly, we try to do any attribute lookups at startup time if possible.
* Every field's tag is encoded to bytes at startup, since it can't change at
runtime.
* Whatever component of the field size we can compute at startup, we do.
* We *avoid* sharing code if doing so would make the code slower and not sharing
does not burden us too much. For example, encoders for repeated fields do
not just call the encoders for singular fields in a loop because this would
add an extra function call overhead for every loop iteration; instead, we
manually inline the single-value encoder into the loop.
* If a Python function lacks a return statement, Python actually generates
instructions to pop the result of the last statement off the stack, push
None onto the stack, and then return that. If we really don't care what
value is returned, then we can save two instructions by returning the
result of the last statement. It looks funny but it helps.
* We assume that type and bounds checking has happened at a higher level.
