This commit makes the following writing improvements:
write_to_vec
And the following reading improvements:
- Removes an unnecessary type annotation.
-
Fixes a dangerous unchecked slice access. Imagine a slice
[0x80]
--
the current code will read past the end of the slice some number of
bytes. The bounds check at the end will subsequently trigger, unless
something bad (like a crash) happens first. The cost of doing bounds
check in the loop body is negligible. - Avoids a mask on the final byte.
And the following improvements for both reading and writing:
-
Changes
for
toloop
for the loops, avoiding an unnecessarycondition on each iteration. This also removes the need for
leb128_size
.
All of these changes give significant perf wins, up to 5%.
