Types

type AliasLookup

type AliasLookup interface {
	Lookup(alias string) (ids.ID, error)
	PrimaryAlias(id ids.ID) (string, error)
}

type Context

type Context struct {
	NetworkID uint32
	SubnetID  ids.ID
	ChainID   ids.ID
	NodeID    ids.ShortID

	XChainID    ids.ID
	AVAXAssetID ids.ID

	Log                 logging.Logger
	DecisionDispatcher  EventDispatcher
	ConsensusDispatcher EventDispatcher
	Lock                sync.RWMutex
	Keystore            keystore.BlockchainKeystore
	SharedMemory        atomic.SharedMemory
	BCLookup            AliasLookup
	SNLookup            SubnetLookup
	Namespace           string

	// Epoch management
	EpochFirstTransition time.Time
	EpochDuration        time.Duration
	Clock                timer.Clock

	// snowman++ attributes
	ValidatorState    validators.State  // interface for P-Chain validators
	StakingLeafSigner crypto.Signer     // block signer
	StakingCertLeaf   *x509.Certificate // block certificate
	// contains filtered or unexported fields
}

Context is information about the current execution. [NetworkID] is the ID of the network this context exists within. [ChainID] is the ID of the chain this context exists within. [NodeID] is the ID of this node

func DefaultContextTest

func DefaultContextTest() *Context

func (*Context) Bootstrapped

func (ctx *Context) Bootstrapped()

Bootstrapped marks this chain as done bootstrapping

func (*Context) Epoch

func (ctx *Context) Epoch() uint32

Epoch this context thinks it's in based on the wall clock time.

func (*Context) IsBootstrapped

func (ctx *Context) IsBootstrapped() bool

IsBootstrapped returns true iff this chain is done bootstrapping

type ContextInitializable

type ContextInitializable interface {
	// InitCtx initializes an object provided a *Context object
	InitCtx(ctx *Context)
}

ContextInitializable represents an object that can be initialized given a *Context object

type EventDispatcher

type EventDispatcher interface {
	Issue(ctx *Context, containerID ids.ID, container []byte) error
	// If the returned error is non-nil, the chain associated with [ctx] should shut
	// down and not commit [container] or any other container to its database as accepted.
	// Accept must be called before [containerID] is committed to the VM as accepted.
	Accept(ctx *Context, containerID ids.ID, container []byte) error
	Reject(ctx *Context, containerID ids.ID, container []byte) error
}

type SubnetLookup

type SubnetLookup interface {
	SubnetID(chainID ids.ID) (ids.ID, error)
}
