use doku::Document;
use serde::Serialize;

#[derive(Serialize, Document)]
struct Config {
    /// Database's host
    db_host: String,
}

impl Default for Config {
    fn default() -> Self {
        Self {
            db_host: "localhost".to_string(),
        }
    }
}

let fmt = doku::toml::Formatting {
    layout: doku::toml::Layout::TwoColumns {
        align: true,
        spacing: 1,
    },
    ..Default::default()
};

let doc = doku::to_toml_fmt_val(&fmt, &Config::default());

doku::assert_doc!(r#"
  db_host = "localhost" # Database's host
