type Plugin interface {
	// Version is the version of the plugin's implementation

	// for the plugin can be found.
	SourceURL() string
	// Description is an optional attribute to provide a more detailed

	// Dependencies are the dependencies this plugin has on other plugins.

	// which depends on the 'protoc-gen-go' generated code.

	// DefaultOptions is the set of default options passed to the plugin.
	//
	// For now, all options are string values. This could eventually
	// support other types (like JSON Schema and Terraform variables),
	// where strings are the default value unless otherwise specified.
	//
	// Note that some legacy plugins don't always express their options
	// as key value pairs. For example, protoc-gen-java has an option
	// that can be passed like so:
	//
	//  java_opt=annotate_code
	//
	// In those cases, the option value in this map will be set to
	// the empty string, and the option will be propagated to the
	// compiler without the '=' delimiter.

	// Registry is the registry configuration, which lets the user specify
	// registry dependencies, and other metadata that applies to a specific
	// remote generation registry (e.g. the Go module proxy, NPM registry,
	// etc).
	Registry() *bufpluginconfig.RegistryConfig
	// ContainerImageDigest returns the plugin's source image digest.
	//
	// For now we only support docker image sources, but this
	// might evolve to support others later on.
