A high-performance trie implementation with native Rust backend.
Get Started
$ dotnet add package HyperTrieCoreReadme
HyperTrie
HyperTrie is a hyper optimized C# prefix tree written in Rust. It is currently the fastest C# Trie implementation, about 601% faster than TrieNet.Core 😮💨
Installation
dotnet add package HyperTrieCore --version 1.0.27
Example
const string url = "https://raw.githubusercontent.com/dolph/dictionary/master/enable1.txt";
var client = new HttpClient();
var content = client.GetStringAsync(url).Result;
var allWords = content.Split(new[] { '\r', '\n' }, StringSplitOptions.RemoveEmptyEntries).Select(x => x.ToLower().Trim()).ToList();
var trieNative = new TrieNative(allWords.Count(), 3);
trieNative.BulkInsert(allWords);
Benchmark
Took 505ms to run Trie.Net
Took 84ms to run Trie Native
Limitations
- No OSX64 support, the Rust code uses GXHash and the Github actions runner does not support the necessary CPU instruction sets :(
- To maximize performance it only supports 26 ASCII characters (A-Z), this is optimal for usecases such as a dictionary or spellcheck applications.
