Detailed Description

Quantizes an AZ::u32 into 1, 2, 3, 4, or 5 bytes based on highest bit usage. The format of the serialized value is a sequence of 1's specifying the number of bytes trailing the initial byte, followed by a 0, followed by the bits that make up the actual value. For example, the number 98 decimal (one byte) will be encoded as 0|1100010, and the largest number representable by a u32, 4294967295, will be represented as 11110|111 11111111 11111111 11111111 111111000.

These are the resulting encoding ranges: Bytes Available Bits Range 1 7 127 2 14 ~16K 3 21 ~2M 4 28 ~256M 5 32 ~4B
