// Inlined from @types/connect
//
// These types are inlined, rather than being used from `@types/connect`
// directly, as a trade-off. It avoids needing an additional entry in
// "dependencies" just for types. It avoids TypeScript users of
// elastic-apm-node needing to manually `npm install @types/connect`.
