Overview ¶
Package internal provides functionality for FrostFS Node Object service communication with FrostFS network. The base client for accessing remote nodes via FrostFS API is a FrostFS SDK Go API client. However, although it encapsulates a useful piece of business logic (e.g. the signature mechanism), the Object service does not fully use the client's flexible interface.
In this regard, this package provides functions over base API client necessary for the application. This allows you to concentrate the entire spectrum of the client's use in one place (this will be convenient both when updating the base client and for evaluating the UX of SDK library). So it is expected that all Object service packages will be limited to this package for the development of functionality requiring FrostFS API communication.
