// All statuses are split into two disjoint subsets: successful and failed, and:
// - statuses that implement the build-in error interface are considered failed statuses;
// - all other value types are considered successes (nil is a default success).
//
// In Go code type of success can be determined by a type switch, failure - by a switch with errors.As calls.
// Nil should be considered as a success, and default switch section - as an unrecognized Status.
//
// To convert statuses into errors and vice versa, use functions ErrToStatus and ErrFromStatus, respectively.
// ErrFromStatus function returns nil for successful statuses. However, to simplify the check of statuses for success,
// IsSuccessful function should be used (try to avoid nil comparison).
// It should be noted that using direct typecasting is not a compatible approach.
//
// To transport statuses using the NeoFS API V2 protocol, see StatusV2 interface and FromStatusV2 and ToStatusV2 functions.
