A Tower layer for minifying HTML responses using `minify-html`.

## Usage

Add this to your `Cargo.toml`:

```toml
[dependencies]
tower-minify-html = "0.1.0"
```

## Example

```rust
use axum::{Router, response::Html, routing::get};
use minify_html::Cfg;
use tower_minify_html::MinifyHtmlLayer;

#[tokio::main]
async fn main() {
    let mut cfg = Cfg::new();
    cfg.keep_closing_tags = true;
    cfg.keep_html_and_head_opening_tags = true;
    cfg.keep_comments = false;

    let app = Router::new()
        .route("/", get(handler))
        .layer(MinifyHtmlLayer::new(cfg));

    let listener = tokio::net::TcpListener::bind("0.0.0.0:3000").await.unwrap();
    axum::serve(listener, app).await.unwrap();
}

async fn handler() -> Html<&'static str> {
    Html(
        r#"
        <!DOCTYPE html>
        <html lang="en">
            <head>
                <meta charset="utf-8">
                <title>    Hello    World    </title>
            </head>
            <body>
                <h1>    Hello    World    </h1>
            </body>
        </html>
        "#,
    )
}
```

## Compression

When using this layer with compression (e.g., `tower-http`'s `CompressionLayer`), ensure that `MinifyHtmlLayer` is applied **before** the compression layer in your code (i.e., `MinifyHtmlLayer` should be the inner layer). This ensures that the HTML is minified before it is compressed.

```rust
let app = Router::new()
    .route("/", get(handler))
    .layer(MinifyHtmlLayer::new(cfg))
    .layer(CompressionLayer::new());
```
