Detailed Description

RAII handle returned by watch().

While a WatchHandle is alive the associated callback remains registered. Destroying or resetting the handle automatically deregisters it. Handles are move-only; they cannot be copied.

Example

// Callback fires whenever "textures/hero.png" is reloaded.
auto handle = assets.watch("textures/hero.png", [&](const std::string &path) {
    reloadHeroSprite();
});
// handle goes out of scope → watch is cancelled automatically.
