pub fn encode_composition_table_bytes(table: &[(u32, u32, u32)]) -> Vec<u8> ⓘExpand description
Encode the canonical composition pair table.
Layout: [count: u32 LE] followed by count records of
(first: u32 LE, second: u32 LE, composed: u32 LE) - 12 bytes per
record. Sorted by (first, second) lexicographic so the runtime
helper can binary-search by the combined 64-bit key.
