Function DecodeASN

src/util/asmap.cpp:150–153

// ASN 0 is reserved and used if there isn't a match.
constexpr uint8_t ASN_BIT_SIZES[]{15, 16, 17, 18, 19, 20, 21, 22, 23, 24};

}

// MATCH argument: Values in [2, 511]. The highest set bit determines the match length
// n ∈ [1,8]; the lower n-1 bits are the pattern to compare.
