fast2s

A super-fast Chinese translation tool to translate Traditional Chinese to Simplified Chinese.

Use hashbrown to build the translation state machine.

Usage:

rust let t = "企畫 計畫 企劃 計劃 畫圖 畫畫"; let s = fast2s::convert(k); assert_eq!(&s, "企划 计划 企划 计划 画图 画画");

Benchmark

See simple.rs under benches directory. I compared the result with opencc-rust, simplet2s-rs, and characterconverter. As characterconverter is too slow, I have to change the sample size to 10 to not wait super long.

Test result (convert and return new string):

| tests | fast2s | simplet2s-rs | opencc-rust | character_conver | | ----- | ------ | ------------ | ----------- | ---------------- | | zht | 188us | 729us | 5.98ms | 1.23s | | zhc | 169us | 941us | 6.89ms | 2.87s | | en | 69us | 3.31ms | 13.99ms | 26.11s |

Test result (mutate existing string):

| tests | fast2s | simplet2s-rs | opencc-rust | character_conver | | ----- | ------ | ------------ | ----------- | ---------------- | | zht | 121us | N/A | N/A | N/A | | zhc | 139us | N/A | N/A | N/A | | en | 78us | N/A | N/A | N/A |

Note:

1. benchmark is done with rust 1.56.1.
2. zht means load "mathzht.txt" and translate, zhc means load "mathzhc.txt" (all Simplified Chinese) and translate, en means load "math_en.txt" (all English) and translate.
3. N/A means not supported.

Please do not trust the benchmark result directly, you shall run it in your local environment. See how to run benchmark.
