Macro unocss_classes::uno

macro_rules! uno {
    ($($t:tt)*) => { ... };
}

Builds a single String from provided string-like arguments and transforms Variant Groups in string literals. The transformation is executed at compile time, so dynamic values are not supported. In such scenario, use [to_uno!] instead.

Example

use unocss_classes::uno;

assert_eq!(uno!["text-red"], "text-red");

assert_eq!(
    uno!["text-(blue lg)", "placeholder:(italic text-(red sm))"],
    "text-blue text-lg placeholder:italic placeholder:text-red placeholder:text-sm"
);

let some = Some("text-red");
let none = None::<String>;
let truthy = true;
let falsy = false;
assert_eq!(uno![
        some,
        none,
        "text-green" => truthy,
        "text-black" => falsy,
        "",
        Some("text-white").map(|_| "text-blue"),
        None::<String>,
    ],
    "text-red text-green text-blue"
);

let truthy = true;
assert_eq!(uno!["text-(sm center)" => truthy], "text-sm text-center");
