Expand description

This trait must be implemented by any plugin type, it not only provides a plugin id, but also provides lifecycle methods which implementors can use to manage resources owned by the plugin.

Required methods

Return the plug-in identifier for this instance. In general a unique format that also provides some debug/trace value is to use the package/module path as shown below.

const PLUGIN_ID: &str = concat!(env!("CARGO_PKG_NAME"), "::", module_path!(), "::MyPlugin");

Called by the plugin manager after the registration process is complete.

Called by the plugin manager once a plugin has been de-registered but before the library is closed.
