triehash 0.3-2 (arm64 binary) in ubuntu focal

 TrieHash generates perfect hash functions as C code which then gets
 compiled into optimal machine code as part of the usual program compilation.
 .
 TrieHash works by translating a list of strings to a trie, and then converting
 the trie to a set of recursive switch statements; first switching by length,
 and then switching by bytes.
 .
 TrieHash has various optimizations such as processing multiple bytes at once
 (on GNU C), and shortcuts for reducing the complexity of case-insensitive
 matching (ASCII only). Generated code performs substantially faster than
 gperf, but is larger.
 .
 TrieHash was written for use in APT.
