Function std.uni.toTrie
Convenience function to construct optimal configurations for
packed Trie from any set
of code points.
auto toTrie(ulong level, Set)
(
Set set
)
if (isCodepointSet!Set);
The parameter level
indicates the number of trie levels to use,
allowed values are: 1, 2, 3 or 4. Levels represent different trade-offs
speed-size wise.
Level 1 is fastest and the most memory hungry (a bit array).
Level 4 is the slowest and has the smallest footprint.
See the Synopsis section for example.
Note
Level 4 stays very practical (being faster and more predictable)
compared to using direct lookup on the set
itself.
