This implements the core logic of the compression scheme used to compactly +//! encode the Unicode character classes. +//! +//! The primary idea is that we 'flatten' the Unicode ranges into an enormous +//! bitset. To represent any arbitrary codepoint in a raw bitset, we would need +//! over 17 kilobytes of data per character set -- way too much for our +//! purposes. +//! +//! We have two primary goals with the encoding: we want to be compact, because +//! these tables often end up in ~every Rust program (especially the +//! grapheme_extend table, used for str debugging), including those for embedded +//! targets (where space is important). We also want to be relatively fast, +//! though this is more of a nice to have rather than a key design constraint. +//! In practice, due to modern processor design these two are closely related. +//! +//! The encoding scheme here compresses the bitset by first deduplicating the +//! "words" (64 bits on all platforms). In practice very few words are present +//! in most data sets. +//! +//! This gives us an array that maps `u8 -> word` (if we ever went beyond 256 +//! words, we could go to u16 -> word or have some dual compression scheme +//! mapping into two separate sets; currently this is not dealt with). +//! +//! With that scheme, we now have a single byte for every 64 codepoints. We +//! further group these by 16 (arbitrarily chosen), and again deduplicate and +//! store in an array (u8 -> [u8; 16]). +//! +//! The indices into this array represent ranges of 64*16 = 1024 codepoints. +//! +//! This already reduces the top-level array to at most 1,086 bytes, but in +//! practice we usually can encode in far fewer (the first couple Unicode planes +//! are dense). +//! +//! The last byte of this top-level array is pulled out to a separate static +//! and trailing zeros are dropped; this is simply because grapheme_extend and +//! case_ignorable have a single entry in the 896th entry, so this shrinks them +//! down considerably. + +use crate::fmt_list;
