Key Characteristics

  • ROM path is always zero-allocation — no GC pressure regardless of request size
  • Multi-segment linearization provides ROM-speed parsing with a single upfront allocation
  • Incomplete input (no \r\n\r\n) returns false with zero allocation
  • SIMD-accelerated validation (SearchValues<byte>, IndexOfAnyExcept) keeps the HardenedParser within ~1.4-1.6x of the unvalidated FlexibleParser
  • All RequestSemantics checks are zero-allocation
