func InitLogCtxHandler

func InitLogCtxHandler(logger *zerolog.Logger) func(next http.Handler) http.Handler

InitLogCtxHandler is a middleware to initialize the LogContext in the standard context.

func LogContextHandler

func LogContextHandler(op string) func(http.Handler) http.Handler

LogContextHandler is a middleware to update the logger with a context using the operation and the current ApplicationContext in the Context.

func LogHTTPHandler

func LogHTTPHandler(next http.Handler) http.Handler
