// Client is a wrapper over raw NeoFS API client.
|
|
//
|
|
// It is not allowed to override client's behaviour:
|
|
// the parameters for the all operations are write-only
|
|
// and the results of the all operations are read-only.
|
|
//
|
|
// Working client must be created via constructor New.
|
|
// Using the Client that has been created with new(Client)
|
|
// expression (or just declaring a Client variable) is unsafe
|
|
// and can lead to panic.
|
|
//
|
|
// Each method which produces a NeoFS API call may return a server response.
|
|
// Status responses are returned in the result structure, and can be cast
|
|
// to built-in error instance (or in the returned error if the client is
|
|
// configured accordingly). Certain statuses can be checked using `apistatus`
|
|
// and standard `errors` packages.
|
|
// All possible responses are documented in methods, however, some may be
|
|
// returned from all of them (pay attention to the presence of the pointer sign):
|
|
// - *apistatus.ServerInternal on internal server error;
|
|
// - *apistatus.SuccessDefaultV2 on default success.
