Converts English lettering to Kana.
Please see the [wiki](https://github.com/spenserblack/to-kana-rs/wiki) to get supported inputs.

## Basic Usage
### As Library
#### Using `to_kana!`
Check out [docs.rs](https://docs.rs/to-kana/) to get all available formats for `to_kana!`

```rust
use to_kana::to_kana;

// こんにちは、ワールド！
let hello_world = to_kana!("{:H}{:K}", "konnichiha,", "wa-rudo!").unwrap();

// Half-width ｶﾀｶﾅ works too!
let half = to_kana!("Half-width {:K/2} works too!", "katakana").unwrap();
```

#### The Old Ways
```rust
use to_kana::ToKana;

let hello = "konnichiha,".hira().unwrap(); // Works on &str
let world = String::from("wa-rudo!").kata().unwrap(); // And String!

println!("{}{}", hello, world)); // こんにちは、ワールド！
```
```rust
use to_kana::{
    hira, // Hiragana
    kata, // Katakana
};

let hello = hira("konnichiha,").unwrap();
let world = kata("wa-rudo!").unwrap();

println!("{}{}", hello, world); // こんにちは、ワールド！
```

What if you don't want to just convert to Kana? What if you want to convert to small, half-width Katakana? You can!
```rust
use to_kana::{
    ToKana,
    SmallKana,
    HalfWidth,
};

// Not to be confused with "ヤ", "ャ" or "ﾔ"
assert_eq!("ｬ", "ya".kata().small().half_width().unwrap());
```
