Functions

func AddAccount 

func AddAccount(t *testing.T, tree *State, store cbor.IpldStore, addr address.Address)

func Diff 

func Diff(oldTree, newTree *State) (map[string]types.Actor, error)

func MustCommit 

func MustCommit(st State) cid.Cid

MustCommit flushes the state or panics if it can't.

func MustGetActor 

func MustGetActor(st State, a address.Address) (*types.Actor, bool)

MustGetActor gets the actor or panics if it can't.

func MustSetActor 

func MustSetActor(st State, address address.Address, actor *types.Actor) cid.Cid

MustSetActor sets the actor or panics if it can't.

func UpdateAccount 

func UpdateAccount(t *testing.T, tree *State, addr address.Address, fn func(*types.Actor))

Types

type ActorKey 

type ActorKey = address.Address

type AdtStore 

type AdtStore struct{ cbor.IpldStore }

func (*AdtStore) Context 

func (a *AdtStore) Context() context.Context

type Root 

type Root = cid.Cid

type State 

type State struct {
	Store cbor.IpldStore
	// contains filtered or unexported fields
}

state stores actors state by their ID.

func LoadState 

func LoadState(ctx context.Context, cst cbor.IpldStore, c cid.Cid) (*State, error)

func NewFromString 

func NewFromString(t *testing.T, s string, store cbor.IpldStore) *State

NewFromString sets a state tree based on an int.

TODO: we could avoid this if write a test cborStore that can map test cids to test states.

func NewState 

func NewState(cst cbor.IpldStore, ver StateTreeVersion) (*State, error)

func NewStateWithBuiltinActor 

func NewStateWithBuiltinActor(t *testing.T, store cbor.IpldStore, ver StateTreeVersion) (*State, error)

func (*State) At 

func (st *State) At(root Root) error

func (*State) ClearSnapshot 

func (st *State) ClearSnapshot()

func (*State) DeleteActor 

func (st *State) DeleteActor(ctx context.Context, addr ActorKey) error

func (*State) Flush 

func (st *State) Flush(ctx context.Context) (cid.Cid, error)

func (*State) ForEach 

func (st *State) ForEach(f func(ActorKey, *types.Actor) error) error

func (*State) GetActor 

func (st *State) GetActor(ctx context.Context, addr ActorKey) (*types.Actor, bool, error)

ToDo Return nil if it is actor not found[ErrActorNotFound],Because the basis for judgment is: err != nil ==> panic ??? GetActor returns the actor from any type of `addr` provided.

func (*State) GetStore 

func (st *State) GetStore() cbor.IpldStore

func (*State) LookupID 

func (st *State) LookupID(addr ActorKey) (address.Address, error)

LookupID gets the ID address of this actor's `addr` stored in the `InitActor`.

func (*State) MutateActor 

func (st *State) MutateActor(addr ActorKey, f func(*types.Actor) error) error

func (*State) RegisterNewAddress 

func (st *State) RegisterNewAddress(addr ActorKey) (address.Address, error)

func (*State) Revert 

func (st *State) Revert() error

func (*State) SetActor 

func (st *State) SetActor(ctx context.Context, addr ActorKey, act *types.Actor) error

func (*State) Snapshot 

func (st *State) Snapshot(ctx context.Context) error

func (*State) Version 

func (st *State) Version() StateTreeVersion

Version returns the version of the StateTree data structure in use.

type StateInfo0 

type StateInfo0 struct{} //nolint

TODO: version this.

func (*StateInfo0) MarshalCBOR 

func (t *StateInfo0) MarshalCBOR(w io.Writer) error

func (*StateInfo0) UnmarshalCBOR 

func (t *StateInfo0) UnmarshalCBOR(r io.Reader) error

type StateRoot 

type StateRoot struct {
	// State tree version.
	Version StateTreeVersion
	// Actors tree. The structure depends on the state root version.
	Actors cid.Cid
	// Info. The structure depends on the state root version.
	Info cid.Cid
}

func (*StateRoot) MarshalCBOR 

func (t *StateRoot) MarshalCBOR(w io.Writer) error

func (*StateRoot) UnmarshalCBOR 

func (t *StateRoot) UnmarshalCBOR(r io.Reader) (err error)

type StateTreeVersion 

type StateTreeVersion uint64 //nolint

const (
	// StateTreeVersion0 corresponds to actors < v2.
	StateTreeVersion0 StateTreeVersion = iota
	// StateTreeVersion1 corresponds to actors v2
	StateTreeVersion1
	// StateTreeVersion2 corresponds to actors v3.
	StateTreeVersion2
	// StateTreeVersion3 corresponds to actors v4.
	StateTreeVersion3
	// StateTreeVersion4 corresponds to actors v5 and above.
	StateTreeVersion4
	// StateTreeVersion5 corresponds to actors v10 and above.
	StateTreeVersion5
)

func VersionForNetwork added in v1.0.4 

func VersionForNetwork(ver network.Version) (StateTreeVersion, error)

VersionForNetwork returns the state tree version for the given network version.

type Tree 

type Tree interface {
	GetActor(ctx context.Context, addr ActorKey) (*types.Actor, bool, error)
	SetActor(ctx context.Context, addr ActorKey, act *types.Actor) error
	DeleteActor(ctx context.Context, addr ActorKey) error
	LookupID(addr ActorKey) (address.Address, error)
	Version() StateTreeVersion

	Flush(ctx context.Context) (cid.Cid, error)
	Snapshot(ctx context.Context) error
	ClearSnapshot()
	Revert() error

	GetStore() cbor.IpldStore
}

Review: can we get rid of this?
