Variables

var BuildVersion string

BuildVersion is provided to be overridden at build time. Eg. go build -ldflags -X 'main.BuildVersion=...'

Types

type App

type App struct {
	// contains filtered or unexported fields
}

App is the main carbonapi runnable

func New

func New(config cfg.API, logger *zap.Logger, buildVersion string) (*App, error)

New creates a new app

func (*App) Start

func (app *App) Start(logger *zap.Logger) func()

Start starts the app: inits handlers, logger, starts HTTP server
