type TipSetKey 

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

A TipSetKey is an immutable collection of CIDs forming a unique key for a tipset. The CIDs are assumed to be distinct and in canonical order. Two keys with the same CIDs in a different order are not considered equal. TipSetKey is a lightweight value type, and may be compared for equality with ==.

func NewTipSetKey 

func NewTipSetKey(cids ...cid.Cid) TipSetKey

NewTipSetKey builds a new key from a slice of CIDs. The CIDs are assumed to be ordered correctly.

func TipSetKeyFromBytes 

func TipSetKeyFromBytes(encoded []byte) (TipSetKey, error)

TipSetKeyFromBytes wraps an encoded key, validating correct decoding.

func (TipSetKey) Bytes 

func (k TipSetKey) Bytes() []byte

Bytes() returns a binary representation of the key.

func (TipSetKey) Cid added in v1.20.0 

func (k TipSetKey) Cid() (cid.Cid, error)

func (TipSetKey) Cids 

func (k TipSetKey) Cids() []cid.Cid

Cids returns a slice of the CIDs comprising this key.

func (TipSetKey) IsEmpty added in v0.2.8 

func (k TipSetKey) IsEmpty() bool

func (TipSetKey) MarshalCBOR added in v1.17.0 

func (k TipSetKey) MarshalCBOR(writer io.Writer) error

func (TipSetKey) MarshalJSON 

func (k TipSetKey) MarshalJSON() ([]byte, error)

func (TipSetKey) String 

func (k TipSetKey) String() string

String() returns a human-readable representation of the key.

func (TipSetKey) ToStorageBlock added in v1.20.0 

func (k TipSetKey) ToStorageBlock() (block.Block, error)

func (*TipSetKey) UnmarshalCBOR added in v1.17.0 

func (k *TipSetKey) UnmarshalCBOR(reader io.Reader) error

func (*TipSetKey) UnmarshalJSON
