Design decisions
No narrow int types on input
Pack methods accept plain int rather than narrow PHPStan types like Int8 or Int32. This is intentional: requiring
callers to carry and assert narrow types would flood driver code with redundant checks and type imports. Thus, we've
decided to keep the validation on our side.
Bounds are checked with assert(), which means zero overhead
in production when assertions are disabled (zend.assertions = -1).
No object wrappers for 8/16/32-bit
8/16/32-bit integers are represented as native PHP int, not value objects. This avoids allocation and method-call
overhead on every pack/unpack — important in tight loops typical of binary protocol parsing.
64-bit integers
64-bit values use BcMath\Number
to handle the full unsigned range beyond PHP_INT_MAX:
