clsx-r

A Rust macro utility for conditionally constructing strings, primarily used for CSS class names. Inspired by the JavaScript clsx package.

Installation

Add this to your Cargo.toml:

[dependencies]
clsx-r = "0.1.0"

Usage

use clsx_r::clsx;

fn main() {
    // Basic usage
    let classes = clsx!("foo", "bar");  // => "foo bar"

    // With conditions
    let is_active = true;
    let is_disabled = false;
    let classes = clsx!(
        "btn",
        "primary",
        "active" => is_active,
        "disabled" => is_disabled
    );  // => "btn primary active"

    // With dynamic values
    let dynamic_class = "special";
    let classes = clsx!(
        "base",
        dynamic_class,
        "highlighted" => true
    );  // => "base special highlighted"
}

Features

• Simple string concatenation
• Conditional class names
• Supports static and dynamic strings
• Filters out empty strings automatically
• Zero dependencies

API

The clsx! macro accepts:

1. Simple string literals or expressions:

   clsx!("class1", "class2")
   

2. Conditional classes using the => syntax:

   clsx!("class1" => condition, "class2" => other_condition)
   

3. Mixed usage:

   clsx!("static", dynamic_var, "conditional" => condition)
