Functions

func AsContainerSource 

func AsContainerSource(w *Client) containercore.Source

AsContainerSource provides container Source interface from Wrapper instance.

func Delete 

func Delete(c *Client, witness core.RemovalWitness) error

Delete marshals container ID, and passes it to Wrapper's Delete method along with signature and session token.

Returns error if container ID is nil.

func DeletionInfo added in v0.37.0 

func DeletionInfo(c deletionInfo, cnr cid.ID) (*containercore.DelInfo, error)

func Get 

func Get(c getContainer, cnr cid.ID) (*containercore.Container, error)

Get marshals container ID, and passes it to Wrapper's Get method.

func Put 

func Put(c *Client, cnr containercore.Container) (*cid.ID, error)

Put marshals container, and passes it to Wrapper's Put method along with sig.Key() and sig.Sign().

Returns error if container is nil.

Types

type AnnounceLoadPrm 

type AnnounceLoadPrm struct {
	client.InvokePrmOptional
	// contains filtered or unexported fields
}

AnnounceLoadPrm groups parameters of AnnounceLoad operation.

func (*AnnounceLoadPrm) SetAnnouncement 

func (a2 *AnnounceLoadPrm) SetAnnouncement(a container.SizeEstimation)

SetAnnouncement sets announcement.

func (*AnnounceLoadPrm) SetReporter 

func (a2 *AnnounceLoadPrm) SetReporter(key []byte)

SetReporter sets public key of the reporter.

type Client 

type Client struct {
	// contains filtered or unexported fields
}

Client is a wrapper over StaticClient which makes calls with the names and arguments of the FrostFS Container contract.

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.

func NewFromMorph 

func NewFromMorph(cli *client.Client, contract util.Uint160, fee fixedn.Fixed8, opts ...Option) (*Client, error)

NewFromMorph returns the wrapper instance from the raw morph client.

Specified fee is used for all operations by default. If WithCustomFeeForNamedPut is provided, the customized fee is used for Put operations with named containers.

func (*Client) AnnounceLoad 

func (c *Client) AnnounceLoad(p AnnounceLoadPrm) error

AnnounceLoad saves container size estimation calculated by storage node with key in FrostFS system through Container contract call.

Returns any error encountered that caused the saving to interrupt.

func (*Client) ContainersOf 

func (c *Client) ContainersOf(idUser *user.ID) ([]cid.ID, error)

ContainersOf returns a list of container identifiers belonging to the specified user of FrostFS system. If idUser is nil, returns the list of all containers.

If remote RPC does not support neo-go session API, fallback to List() method.

func (Client) ContractAddress 

func (c Client) ContractAddress() util.Uint160

ContractAddress returns the address of the associated contract.

func (*Client) Delete 

func (c *Client) Delete(p DeletePrm) (uint32, error)

Delete removes the container from FrostFS system through Container contract call.

Returns valid until block and any error encountered that caused the removal to interrupt.

If TryNotary is provided, calls notary contract.

func (*Client) DeletionInfo added in v0.37.0 

func (c *Client) DeletionInfo(cid []byte) (*containercore.DelInfo, error)

func (*Client) Get 

func (c *Client) Get(cid []byte) (*containercore.Container, error)

Get reads the container from FrostFS system by binary identifier through Container contract call.

If an empty slice is returned for the requested identifier, storage.ErrNotFound error is returned.

func (*Client) GetEACL 

func (c *Client) GetEACL(cnr cid.ID) (*container.EACL, error)

GetEACL reads the extended ACL table from FrostFS system through Container contract call.

Returns apistatus.EACLNotFound if eACL table is missing in the contract.

func (*Client) GetUsedSpaceEstimations 

func (c *Client) GetUsedSpaceEstimations(id EstimationID) (*Estimations, error)

GetUsedSpaceEstimations returns a list of container load estimations by ID. The list is composed through Container contract call.

func (*Client) ListLoadEstimationsByEpoch 

func (c *Client) ListLoadEstimationsByEpoch(epoch uint64) ([]EstimationID, error)

ListLoadEstimationsByEpoch returns a list of container load estimations for to the specified epoch. The list is composed through Container contract call.

func (Client) Morph 

func (c Client) Morph() *client.Client

Morph returns raw morph client.

func (*Client) Put 

func (c *Client) Put(p PutPrm) error

Put saves binary container with its session token, key and signature in FrostFS system through Container contract call.

Returns calculated container identifier and any error encountered that caused the saving to interrupt.

If TryNotary is provided, calls notary contract.

func (*Client) StartEstimation 

func (c *Client) StartEstimation(p StartEstimationPrm) error

StartEstimation votes to produce start estimation notification.

func (*Client) StopEstimation 

func (c *Client) StopEstimation(p StopEstimationPrm) error

StopEstimation votes to produce stop estimation notification.

type DeletePrm 

type DeletePrm struct {
	client.InvokePrmOptional
	// contains filtered or unexported fields
}

DeletePrm groups parameters of Delete client operation.

func (*DeletePrm) SetCID 

func (d *DeletePrm) SetCID(cid []byte)

SetCID sets container ID.

func (*DeletePrm) SetKey added in v0.37.0 

func (d *DeletePrm) SetKey(key []byte)

SetKey sets public key.

func (*DeletePrm) SetSignature 

func (d *DeletePrm) SetSignature(signature []byte)

SetSignature sets signature.

func (*DeletePrm) SetToken 

func (d *DeletePrm) SetToken(token []byte)

SetToken sets session token.
