fast2s

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

Use fst to build the translation state machine.

Usage:

let t = "企畫 計畫 企劃 計劃 畫圖 畫畫";
let s = fast2s::convert(k);
assert_eq!(&s, "企画 计画 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 character_converter. As character_converter is too slow, I have to change the sample size to 10 to not wait super long.

Test result (convert and return new string):

Test result (mutate existing string):

Note:

1. zht means load "math_zht.txt" and translate, zhc means load "math_zhc.txt" (all Simplified Chinese) and translate, en means load "math_en.txt" (all English) and translate.
2. N/A means not supported.

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