type PluginLoader struct {

	// PluginDir is the directory where plugins will be loaded from
	PluginDir string
}

PluginLoader uses the plugin mechanism introduced in Go 1.8 to laod compiled plugins from a given directory.

func (l *PluginLoader) Load(id string) (plugins.Plugin, error)

Load the given plugin using the native plugin support introduced in Go 1.8

Plugins must follow the plugin conventions:

Be present in the configured 'PluginDir/name.so' (plugin name in lowercase)
Must export a variable named 'Name' (the capitalized name of the plugin) of type 'enforcer.Plugin'

func (l *PluginLoader) Unload(id string) error

Unload releases the resources used by a plugin. In Go 1.8, closing an open plugin is still not supported, so this method does nothing.
