Constants

const (
	// CodecVersionV0 is the v1.23.x ("Apricot/Banff") wire layout. It is
	// retained as a READ-ONLY decoder so that pre-codec-v1 blocks on
	// disk continue to deserialize and so that v0-derived BlockIDs and
	// TxIDs remain stable. All write paths MUST use CodecVersionV1.
	CodecVersionV0 = txs.CodecVersionV0

	// CodecVersionV1 is the current canonical block-codec wire layout.
	// Every block built by this binary is written at v1.
	CodecVersionV1 = txs.CodecVersionV1

	// CodecVersion is the canonical write version. All Marshal call
	// sites in this package use CodecVersion so that any future bump of
	// the write target updates exactly one symbol.
	CodecVersion = CodecVersionV1

Variables

var (
	// Codec is the v1 write/read codec.Manager. It carries ONLY the v1
	// slot map and so decodes only v1-prefixed bytes. v0 bytes must go
	// through ParseBytes (which routes to v0Codec for version 0).
	Codec codec.Manager

	// GenesisCodec is the v1 large-size codec.Manager. Same v1 slot map
	// as Codec but with an unbounded maximum size for genesis decode and
	// state-read fallback paths.
	GenesisCodec codec.Manager
)

var ErrShortBytes = errors.New("block bytes too short for codec version prefix")

ErrShortBytes is returned when the input is shorter than the 2-byte codec-version prefix.

Functions

func RegisterBlockTypes added in v1.26.35 

func RegisterBlockTypes(targetCodec linearcodec.Codec) error

RegisterBlockTypes registers the canonical v1 block type IDs. There is exactly one type per block kind: ProposalBlock, AbortBlock, CommitBlock, StandardBlock. Tx types come from txs.RegisterTypes (which registers the v1 tx slot layout).

func RegisterGenesisType added in v1.16.56 

func RegisterGenesisType(val interface{}) error

RegisterGenesisType registers a type with the GenesisCodec at the canonical write version (v1). This is used by other packages (e.g. state) to register types that are only ever encountered in genesis bytes. The v0 codec is closed to external registration — its slot map is frozen at the v1.23.x layout.

Types

type AbortBlock added in v1.26.35 

type AbortBlock struct {
	Time        uint64 `serialize:"true" json:"time"`
	CommonBlock `serialize:"true"`
}

AbortBlock is the canonical P-Chain abort outcome of a ProposalBlock.

func NewAbortBlock added in v1.26.35 

func NewAbortBlock(
	timestamp time.Time,
	parentID ids.ID,
	height uint64,
) (*AbortBlock, error)

func (*AbortBlock) InitRuntime added in v1.26.35 

func (*AbortBlock) InitRuntime(*runtime.Runtime)

func (*AbortBlock) Initialize added in v1.26.35 

func (*AbortBlock) Initialize(context.Context) error

func (*AbortBlock) Timestamp added in v1.26.35 

func (b *AbortBlock) Timestamp() time.Time

func (*AbortBlock) Txs added in v1.26.35 

func (*AbortBlock) Txs() []*txs.Tx

func (*AbortBlock) Visit added in v1.26.35 

func (b *AbortBlock) Visit(v Visitor) error

type Block 

type Block interface {
	RuntimeInitializable
	ID() ids.ID
	Parent() ids.ID
	Bytes() []byte
	Height() uint64

	// Txs returns list of transactions contained in the block
	Txs() []*txs.Tx

	// Visit calls [visitor] with this block's concrete type
	Visit(visitor Visitor) error
	// contains filtered or unexported methods
}

Block defines the common stateless interface for all blocks

func Parse 

func Parse(c codec.Manager, b []byte) (Block, error)

Parse decodes a block byte stream produced by either the v0 (v1.23.x) or v1 (current) block codec. The codec.Manager argument selects the SIZE class — Codec (1 MiB max) or GenesisCodec (unbounded). The actual VERSION is taken from the 2-byte wire prefix and dispatched to the matching slot map.

Parse never re-marshals the input; BlockID = hash(b) verbatim and b is stashed on the returned block's CommonBlock. This is the byte-preserving path that keeps BlockIDs (and inner TxIDs) stable across the v0->v1 migration.

c must be one of block.Codec or block.GenesisCodec. The v0 codec is selected internally based on the size class of c. Other codecs are rejected with codec.ErrUnknownVersion.
