The offline thesaurus library for Rust that can use both [wordnet](https://wordnet.princeton.edu/) and [moby](https://en.wikipedia.org/wiki/Moby_Project) thesauruses.

Add to `Cargo.toml` for wordnet:
```toml
thesaurus = "0.5"
```

Add to `Cargo.toml` for just moby *(wordnet and static are on by default)*:
```toml
thesaurus = { version = "0.5", features = ["moby","static"], default_features = false }
```

## Crate Feature "`static`"
`static` is a feature that is turned on by default that the thesaurus dictionary to be stored in memory during runtime. This allows calls to [`dict`] and [`synonyms`] to be **2.5-3x faster after initialization** with the added downside of increased memory usage. To turn off `static`, use the `default_features = false` option.

## Basic Example
```rust
use std::{env, process};

fn main() {
    let args = env::args().collect::<Vec<String>>();

    let word: String = match args.get(1) {
        Some(word) => word.to_string(),
        None => {
            eprintln!("Must include a word as an argument");
            process::exit(1);
        }
    };

    let synonyms = thesaurus::synonyms(&word);
    let num_words = thesaurus::dict().len();

    cfg_if::cfg_if! {
        if #[cfg(all(feature = "moby", feature = "wordnet"))] {
            print!("both wordnet and moby have ");
        } else if #[cfg(feature = "moby")] {
            print!("moby has ");
        } else if #[cfg(feature = "wordnet")] {
            print!("wordnet has ");
        }
    }

    println!("{num_words} words indexed, and {} synonyms for \"{word}\"...", synonyms.len());
    println!("synonyms...");
    for x in &synonyms {
        println!("   {x}");
    }
}
```

### Wordnet Output
```shell
 $ cargo r -rq --example simple -- good
```

```
wordnet has 125701 words indexed, and 107 synonyms for "good"...

```

### Moby Output
```shell
 $ cargo r -rq --example simple --no-default-features --features=moby -- good
```

```
