A rust library to generate sitemaps.

It uses the [quick-xml](https://github.com/tafia/quick-xml) so it should be fast.

## Example

To run the examples use `cargo run --example gen_sitemap`

```rust
use chrono::prelude::*;
use sitewriter::*;

fn main() {
    let mut sitemap = Sitemap::new();
    sitemap.urls.push(Url::new("https://edgarluque.com/projects"));

    sitemap.urls.push(Url {
        loc: "https://edgarluque.com/",
        changefreq: Some(ChangeFreq::Daily),
        priority: Some(1.0),
        lastmod: Some(Utc::now()),
    });

    sitemap.urls.push(Url {
        loc: "https://edgarluque.com/blog",
        changefreq: Some(ChangeFreq::Weekly),
        priority: Some(0.8),
        lastmod: Some(Utc::now()),
    });

    sitemap.urls.push(Url {
        loc: "https://edgarluque.com/blog/sitewriter",
        changefreq: Some(ChangeFreq::Never),
        priority: Some(0.5),
        lastmod: Some(Utc.ymd(2020, 11, 22).and_hms(15, 10, 15)),
    });

    sitemap.urls.push(Url {
        loc: "https://edgarluque.com/blog/some-future-post",
        changefreq: Some(ChangeFreq::Never),
        priority: Some(0.5),
        lastmod: Some(Utc.from_utc_datetime(&Local.ymd(2020, 12, 5).and_hms(12, 30, 0).naive_utc())),
    });


    let result = sitemap.into_str();
    println!("{}", result);
}
```

Prints the following:
```xml
<?xml version="1.0" encoding="UTF-8"?>
<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">

        <loc>https://edgarluque.com/projects</loc>
