thesaurus-rs

The offline thesaurus library for Rust that can use both wordnet and moby backends.

Add to Cargo.toml for wordnet:

thesaurus = { version = "0.4.0", features = ["wordnet"] }

Add to Cargo.toml for moby (wordnet is on by default):

thesaurus = { version = "0.4.0", features = ["moby"], default_features = false }

Both moby and wordnet have the same APIs, but they are included in different modules so you can use both in the same binary (in theory).

Backend Comparison

Basic Wordnet Example

use thesaurus::wordnet;

fn main() {
    let word = "good";
    let results = wordnet::synonyms(word).unwrap();

    println!("Found {} results for {}:", results.len(), word);

    for word in results {
        println!("  {word}");
    }
}

Result:

Found 107 results for good:
  skilled
  skilful
  practiced
  skillful
  expert
  adept
  proficient
