Methods

static void WriteCompressedInt64(Stream stream, Int64 value)

Writes an Int64 value in “compressed” format. This uses the UInt64 compression logic, with an extra twist. -1 has all bytes set, meaning that if we just want to use the “compression” on it, it will occupy 10 bytes. So, instead, we shift the sign bit to the right and invert all the bits when a value is negative. In this way, the values 0, -1, 1, -2, 2, -3, 3 etc are actually written as 0, 1, 2, 3, 4, 5, 6, keeping just one byte instead of 4 (no compression) or 10 (bad compression for negatives).
