|
Takes a buffer and reads a length coded string from the start.
|
|
This is how Length coded strings work
|
|
If the string is 250 bytes long or smaller, then it looks like this:
|
|
<-- 1b -->
|
+----------+-------------------------
|
| length | a string goes here
|
+----------+-------------------------
|
|
If the string is bigger than 250, then it looks like this:
|
|
<- 1b -><- 2/3/8 ->
|
+------+-----------+-------------------------
|
| type | length | a string goes here
|
+------+-----------+-------------------------
|
|
if type == ü:
|
length is code in next 2 bytes
|
elif type == ý:
|
length is code in next 3 bytes
|
elif type == þ:
|
length is code in next 8 bytes
|
|
NULL has a special value. If the buffer starts with û then
|
it's a NULL and we return None as value.
|
|
Returns a tuple (trucated buffer, bytes).
