简单的标签化 ID

带有关联类型标签的简单 ID。

use slid::Id;

struct User;
let player_a = Id::<User>::new_random();
let player_b = Id::<User>::new_random();

// For all practical purposes, we can assume that 2 random IDs will be unique and different
assert_ne!(player_a, player_b);


// The label generic helps avoid mixups:
struct Product;
fn delete_product(id: Id<Product>) {}

// Doesn't compile, because Id<User> and Id<Player> are different
// delete_product(player_a);

// But you can explicitly cast the label if needed:
delete_product(player_a.cast_label());

替代方案

注意：此库不试图符合任何 UUID 标准。随机 ID 是简单的随机。如果您需要标准的 UUID，请查看 uuid
