Method UseOnce

core/router/api_builder.go:1316–1318

(handlers ...context.Handler)

// replace that existing middleware instead.
// To register a middleware for error handlers, look `UseError` method instead.
func (api *APIBuilder) UseOnce(handlers ...context.Handler) {
	api.middleware = context.UpsertHandlers(api.middleware, handlers)
}

// UseGlobal registers handlers that should run at the very beginning.
// It prepends those handler(s) to all routes,
