```

## Sample Code

### 指定日の祝日名を取得
```rust
use jpholiday::jpholiday::JPHoliday;
use jpholiday::chrono::{NaiveDate};
use std::borrow::Borrow;

let jpholiday = JPHoliday::new();

assert_eq!(
    jpholiday.is_holiday_name(NaiveDate::from_ymd(2017, 1, 1).borrow()).unwrap(),
    "元日".to_string()
);

assert_eq!(
    jpholiday.is_holiday_name(NaiveDate::from_ymd(2017, 1, 2).borrow()).unwrap(),
    "元日 振替休日".to_string()
);

assert_eq!(
    jpholiday.is_holiday_name(NaiveDate::from_ymd(2017, 1, 3).borrow()),
    None
);
```

### 指定日が祝日か判定
```rust
use jpholiday::jpholiday::JPHoliday;
use jpholiday::chrono::{NaiveDate};
use std::borrow::Borrow;

let jpholiday = JPHoliday::new();

assert_eq!(
    jpholiday.is_holiday(NaiveDate::from_ymd(2017, 1, 1).borrow()),
    true
);

assert_eq!(
    jpholiday.is_holiday(NaiveDate::from_ymd(2017, 1, 2).borrow()),
    true
);

assert_eq!(
    jpholiday.is_holiday(NaiveDate::from_ymd(2017, 1, 3).borrow()),
    false
);
```

### 指定年の祝日を取得
```rust
use jpholiday::jpholiday::JPHoliday;
use jpholiday::chrono::{NaiveDate};
use std::borrow::Borrow;

let jpholiday = JPHoliday::new();

assert_eq!(
    jpholiday.year_holidays(2017),
    vec![
        (NaiveDate::from_ymd(2017, 1, 1), "元日".to_string()),
