}

Config is our standard protocol for configuration objects.

type HasAuthenticator

type HasAuthenticator interface {
	GetAuthenticator() types.Authenticator
}

HasAuthenticator allows the object to supply a types.Authenticator.

type HasDiagnostics

type HasDiagnostics interface {
	GetDiagnostics() *diag.Diagnostics
}

HasDiagnostics allows the object to supply a diag.Diagnostics.

type HasServeMux

type HasServeMux interface {
	GetServeMux() *http.ServeMux
}

HasServeMux allows the object to provide a http.ServeMux to bind the endpoints to, if the MetricsAddrFlag is not set.

type Template

type Template struct {
	// An optional object for CLI flag registration.
	Config Config
	// An optional default value for [MetricsAddrFlag].
	Metrics string
	// Passed to [cobra.Command.Short].
	Short string
	// Start should return an object that implements zero or more of the
	// capability interfaces in this package.
	Start func(ctx *stopper.Context, cmd *cobra.Command) (started any, err error)
	// Passed to [cobra.Command.Use].
	Use string
