FastFibCode
Ultra-fast Fibonacci encoding/decoding methods. The implementation is based on the Fast Fibonacci Encoding Algorithm and the The Fast Fibonacci Decompression Algorithm, with additional optimizations to achieve even better performance. It is 10–30 times faster than the conventional algorithm (depending on the value distribution).
Basic usage
All values are internally incremented during encoding and decremented during decoding to allow the representation of zero. The maximum supported value is $2^{64}-2$.
using static FastFibCode.Fibonacci;
UInt128 codeForULong = EncodeULong(0x0102030405060708);
ulong codeForUInt = EncodeUInt(0x01020304);
uint codeForShort = EncodeUShort(0x0102);
ushort codeForByte = EncodeByte(0x01);
MyFavoriteBitWriter bw = ...;
// assume lower bits are written first
bw.WriteBits(codeForULong, (int)UInt128.Log2(codeForULong) + 1);
bw.WriteBit(1); // "delimiter"
bw.WriteBits(codeForUInt, BitOperations.Log2(codeForUInt) + 1);
bw.WriteBit(1);
bw.WriteBits(codeForShort, BitOperations.Log2(codeForShort) + 1);
bw.WriteBit(1);
bw.WriteBits(codeForByte, BitOperations.Log2(codeForByte) + 1);
bw.WriteBit(1);
// =============================================================
MyFavoriteBitReader br = ...;
UInt128 code = br.ReadUpToDoubleOnes(); // with final '11'
code ^= UInt128.One << (int)UInt128.Log2(codeForULong); // clear the delimiter '1' bit
ulong value = DecodeAsULong(code);
// ...
