Macro for various algorithm operations

This macro supports multiple random operations, including generating random booleans, random types, random arrays, RGB colors, nanoids, and more.

Examples

use e_utils::algorithm;

fn main() {
    // 生成随机布尔值
    let random_bool = algorithm!();
    println!("随机布尔值: {}", random_bool);

    // 生成随机 u32
    let random_u32: u32 = algorithm!(#u32);
    println!("随机 u32: {}", random_u32);

    // 生成随机数组
    let random_array: [u8; 5] = algorithm!([u8; 5]);
    println!("随机数组: {:?}", random_array);

    // 生成随机 RGB 颜色
    let rgb = algorithm!(rgb 0, 255);
    println!("随机 RGB: {:?}", rgb);

    // 生成默认长度（21）的 nanoid
    let default_nanoid = algorithm!(nanoid);
    println!("默认 nanoid: {}", default_nanoid);

    // 生成自定义长度的 nanoid
    let custom_nanoid = algorithm!(nanoid 10);
    println!("自定义 nanoid: {}", custom_nanoid);

    // 生成指定范围内的随机数
    let random_range = algorithm!(0..100);
    println!("随机数 (0-99): {}", random_range);

    // 生成负数范围内的随机数
    let negative_range = algorithm!((-50)..50);
    println!("随机数 (-50 到 49): {}", negative_range);

    // 生成自定义字母表的 nanoid
    let custom_alphabet_nanoid = algorithm!(nanoid 8, &"abcdef123456".chars().collect::<Vec<char>>());
    println!("自定义字母表 nanoid: {}", custom_alphabet_nanoid);

    // 使用不安全模式生成 nanoid
    let unsafe_nanoid = algorithm!(nanoid unsafe 15);
    println!("不安全模式 nanoid: {}", unsafe_nanoid);

    // 使用不安全模式和自定义字母表生成 nanoid
    let unsafe_custom_nanoid = algorithm!(nanoid unsafe 12, &"ABCDEFGHIJKLMNOPQRSTUVWXYZ".chars().collect::<Vec<char>>());
    println!("不安全模式自定义字母表 nanoid: {}", unsafe_custom_nanoid);
