Struct WatchingPluginManager 

pub struct WatchingPluginManager { /* private fields */ }

Plugin manager with hot-reloading support.

This manager tracks plugin file modification times and can reload plugins when their source files change. This is useful for development workflows where you want to iterate on plugins without restarting.

Example

use rustledger_plugin::WatchingPluginManager;

let mut manager = WatchingPluginManager::new();
manager.load("plugins/my_plugin.wasm")?;

// Check for changes and reload if needed
if manager.check_and_reload()? {
    println!("Plugins reloaded!");
}
