Method AtOrNull

engine/Poseidon/Foundation/Containers/Array.hpp:133–133

Release-checked element access for indices that originate off the wire. Unlike operator[]/Set/Get (whose AssertDebug compiles out under NDEBUG), this bounds-check survives in shipping builds: it returns nullptr instead of indexing out of range, so callers handling attacker-controlled indices can reject rather than read/write past it.

    // survives in shipping builds: it returns nullptr instead of indexing out of range, so
    // callers handling attacker-controlled indices can reject rather than read/write past it.
