Overview

Package voluntaryexits defines an in-memory pool of received voluntary exit events by the beacon node, handling their lifecycle and performing integrity checks before serving them as objects for validators to include in blocks.

Types

type Pool

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

Pool is a concrete implementation of PoolManager.

func NewPool

func NewPool() *Pool

NewPool accepts a head fetcher (for reading the validator set) and returns an initialized voluntary exit pool.

func (*Pool) InsertVoluntaryExit

func (p *Pool) InsertVoluntaryExit(ctx context.Context, state state.ReadOnlyBeaconState, exit *ethpb.SignedVoluntaryExit)

InsertVoluntaryExit into the pool. This method is a no-op if the pending exit already exists, or the validator is already exited.

func (*Pool) MarkIncluded

func (p *Pool) MarkIncluded(exit *ethpb.SignedVoluntaryExit)

MarkIncluded is used when an exit has been included in a beacon block. Every block seen by this node should call this method to include the exit. This will remove the exit from the pending exits slice.

func (*Pool) PendingExits

func (p *Pool) PendingExits(state state.ReadOnlyBeaconState, slot types.Slot, noLimit bool) []*ethpb.SignedVoluntaryExit

PendingExits returns exits that are ready for inclusion at the given slot. This method will not return more than the block enforced MaxVoluntaryExits.

type PoolManager

type PoolManager interface {
	PendingExits(state state.ReadOnlyBeaconState, slot types.Slot, noLimit bool) []*ethpb.SignedVoluntaryExit
	InsertVoluntaryExit(ctx context.Context, state state.ReadOnlyBeaconState, exit *ethpb.SignedVoluntaryExit)
	MarkIncluded(exit *ethpb.SignedVoluntaryExit)
}

PoolManager maintains pending and seen voluntary exits. This pool is used by proposers to insert voluntary exits into new blocks.
