Examples

fn main() {
    let mut context = HashMap::new();

    context.insert("page_links".to_string(), ctx_vec(vec![
        ctx_map([("href", ctx_str("/#about")), ("label", ctx_str("About me"))]),
        ctx_map([("href", ctx_str("/experience")), ("label", ctx_str("Experience"))]),
        ctx_map([("href", ctx_str("/skills")), ("label", ctx_str("Skills"))]),
    ]));

    let template = template("templates/landing-page.html", Some(context));

    let routes = vec![
        Route::new(GET, "/", ResponseContent::Str(
            match &template {
                Ok(template) => template.to_string(),
                Err(_e) => panic!("Could not render template"),
            }
        )),
        Route::new(GET, "/images/*", ResponseContent::FolderAccess)
    ];
    start_server(routes, ServerOptions { address: Some("localhost:8080".to_string()) });
}
