Static wiwi::encoding::z85::TABLE_DECODER

pub static TABLE_DECODER: [u8; 256]

Table of length 256, mapping any u8 to the value it represents

0xff values represent None. Doing it this way instead of Option halves the size of this table (u8 is 1 byte, Option is 2 bytes)

This table could be shrinked to just 96 elements, holding the range 32..128, but keeping it length 256 means it’s possible to index into this table with any arbitrary byte value without going out of bounds, saving a check for a value to be within 32..128.
