Functions

func InitializeDataMaps

func InitializeDataMaps()

InitializeDataMaps initializes all the relevant object maps. This function is called to reset maps and reinitialize them.

Types

type BeaconBlockByRootsReq

type BeaconBlockByRootsReq [][rootLength]byte

BeaconBlockByRootsReq specifies the block by roots request type.

func (*BeaconBlockByRootsReq) MarshalSSZ

func (r *BeaconBlockByRootsReq) MarshalSSZ() ([]byte, error)

MarshalSSZ Marshals the block by roots request type into the serialized object.

func (*BeaconBlockByRootsReq) MarshalSSZTo

func (r *BeaconBlockByRootsReq) MarshalSSZTo(dst []byte) ([]byte, error)

MarshalSSZTo marshals the block by roots request with the provided byte slice.

func (*BeaconBlockByRootsReq) SizeSSZ

func (r *BeaconBlockByRootsReq) SizeSSZ() int

SizeSSZ returns the size of the serialized representation.

func (*BeaconBlockByRootsReq) UnmarshalSSZ

func (r *BeaconBlockByRootsReq) UnmarshalSSZ(buf []byte) error

UnmarshalSSZ unmarshals the provided bytes buffer into the block by roots request object.

type BlobSidecarsByRootReq

type BlobSidecarsByRootReq []*eth.BlobIdentifier

BlobSidecarsByRootReq is used to specify a list of blob targets (root+index) in a BlobSidecarsByRoot RPC request.

func (BlobSidecarsByRootReq) Len

func (s BlobSidecarsByRootReq) Len() int

Len is the number of elements in the collection.

func (BlobSidecarsByRootReq) Less

func (s BlobSidecarsByRootReq) Less(i, j int) bool

Less reports whether the element with index i must sort before the element with index j. BlobIdentifier will be sorted in lexicographic order by root, with Blob Index as tiebreaker for a given root.

func (*BlobSidecarsByRootReq) MarshalSSZ

func (b *BlobSidecarsByRootReq) MarshalSSZ() ([]byte, error)

MarshalSSZ serializes the BlobSidecarsByRootReq value to a byte slice.

func (*BlobSidecarsByRootReq) MarshalSSZTo

func (b *BlobSidecarsByRootReq) MarshalSSZTo(dst []byte) ([]byte, error)

MarshalSSZTo appends the serialized BlobSidecarsByRootReq value to the provided byte slice.

func (*BlobSidecarsByRootReq) SizeSSZ

func (b *BlobSidecarsByRootReq) SizeSSZ() int

SizeSSZ returns the size of the serialized representation.

func (BlobSidecarsByRootReq) Swap

func (s BlobSidecarsByRootReq) Swap(i, j int)

Swap swaps the elements with indexes i and j.

func (*BlobSidecarsByRootReq) UnmarshalSSZ

func (b *BlobSidecarsByRootReq) UnmarshalSSZ(buf []byte) error

UnmarshalSSZ unmarshals the provided bytes buffer into the BlobSidecarsByRootReq value.

type ErrorMessage

type ErrorMessage []byte

ErrorMessage describes the error message type.

func (*ErrorMessage) MarshalSSZ

func (m *ErrorMessage) MarshalSSZ() ([]byte, error)

MarshalSSZ Marshals the error message into the serialized object.

func (*ErrorMessage) MarshalSSZTo

func (m *ErrorMessage) MarshalSSZTo(dst []byte) ([]byte, error)

MarshalSSZTo marshals the error message with the provided byte slice.

func (*ErrorMessage) SizeSSZ

func (m *ErrorMessage) SizeSSZ() int

SizeSSZ returns the size of the serialized representation.

func (*ErrorMessage) UnmarshalSSZ

func (m *ErrorMessage) UnmarshalSSZ(buf []byte) error

UnmarshalSSZ unmarshals the provided bytes buffer into the error message object.

type RPCGoodbyeCode

type RPCGoodbyeCode = primitives.SSZUint64

RPCGoodbyeCode represents goodbye code, used in sync package.

func ErrToGoodbyeCode

func ErrToGoodbyeCode(err error) RPCGoodbyeCode

ErrToGoodbyeCode converts given error to RPC goodbye code.

type SSZBytes

type SSZBytes []byte

SSZBytes is a bytes slice that satisfies the fast-ssz interface.

func (*SSZBytes) HashTreeRoot

func (b *SSZBytes) HashTreeRoot() ([32]byte, error)

HashTreeRoot hashes the uint64 object following the SSZ standard.

func (*SSZBytes) HashTreeRootWith

func (b *SSZBytes) HashTreeRootWith(hh *ssz.Hasher) error

HashTreeRootWith hashes the uint64 object with the given hasher.
