Types

type MapLedger

type MapLedger struct {
	sync.RWMutex
	Registers       map[flow.RegisterID]flow.RegisterValue
	RegisterTouches map[flow.RegisterID]struct{}
	RegisterUpdated map[flow.RegisterID]struct{}
}

A MapLedger is a naive ledger storage implementation backed by a simple map.

This implementation is designed for testing and migration purposes.

func NewMapLedger

func NewMapLedger() *MapLedger

NewMapLedger returns an instance of map ledger (should only be used for testing and migration)

func NewMapLedgerFromPayloads

func NewMapLedgerFromPayloads(payloads []ledger.Payload) *MapLedger

NewMapLedger returns an instance of map ledger with entries loaded from payloads (should only be used for testing and migration)

func (*MapLedger) Delete

func (m *MapLedger) Delete(owner, key string) error

func (*MapLedger) Get

func (m *MapLedger) Get(owner, key string) (flow.RegisterValue, error)

func (*MapLedger) Payloads

func (m *MapLedger) Payloads() []ledger.Payload

func (*MapLedger) Set

func (m *MapLedger) Set(owner, key string, value flow.RegisterValue) error

func (*MapLedger) Touch

func (m *MapLedger) Touch(owner, key string) error

type SimpleView

type SimpleView struct {
	Parent *SimpleView
	Ledger *MapLedger
}

SimpleView provides a simple view for testing and migration purposes.

func NewSimpleView

func NewSimpleView() *SimpleView

func NewSimpleViewFromPayloads

func NewSimpleViewFromPayloads(payloads []ledger.Payload) *SimpleView

func (*SimpleView) AllRegisters

func (v *SimpleView) Delete(owner, key string) error

func (*SimpleView) DropDelta

func (v *SimpleView) DropDelta()

func (*SimpleView) Get
