LGTM, but let's wait for final approval from @DelevoXDG

Nit:

Suggested change

	fun <T> success(value: T): RequestResult<T> = RequestResult(Result.success(value))
	fun <T> failure(throwable: Throwable): RequestResult<T> =
	RequestResult(Result.failure(throwable))
	fun <T> success(value: T) = RequestResult(Result.success(value))
	fun <T> failure(throwable: Throwable) = RequestResult(Result.failure(throwable))

[franciszekjob]

Actually in failure we have to keep RequestResult<T>, as there is not enough information to infer the type.
