func Load 

func Load(ctx context.Context, config Config, repo Repository) (_ *Catalog, err error)

Load loads and configures plugins defined in the configuration. The given catalog is populated with plugin and service facades for versions implemented by the loaded plugins. The returned io.Closer can be used to close down the loaded plugins, at which point, all facades bound to the given catalog are considered invalidated. If any plugin fails to load or configure, all plugins are unloaded, the catalog is cleared, and the function returns an error.

type ServiceRepo added in v1.0.0 

type ServiceRepo interface {
	// Binder returns a function that is used by the catalog system to "bind"
	// the facade returned by selected version to the repository. It MUST
	// return void and take a single argument of type X, where X can be
	// assigned to by any of the facade implementation types returned by the
	// provided versions (see Versions).
	Binder() any

	// Versions returns the versions supported by the repository, ordered by
	// most to least preferred. The first version supported by the plugin will
	// be used. When a deprecated version is bound, warning messaging will
	// recommend the first version in the list as a replacement, unless it is
	// also deprecated.
	Versions() []Version

	// Clear is called when loading fails to clear the repository of any
	// previously bound facades.
	Clear()
