Functions ¶

func GasEstimateCallWithGas ¶

func GasEstimateCallWithGas(
	ctx context.Context,
	cstore ChainStoreAPI,
	smgr StateManagerAPI,
	mpool MessagePoolAPI,
	msgIn *types.Message,
	currTs *types.TipSet,
) (*api.InvocResult, []types.ChainMsg, *types.TipSet, error)

GasEstimateCallWithGas invokes a message "msgIn" on the earliest available tipset with pending messages in the message pool. The function returns the result of the message invocation, the pending messages, the tipset used for the invocation, and an error if occurred. The returned information can be used to make subsequent calls to CallWithGas with the same parameters.

func GasEstimateFeeCap ¶

func GasEstimateFeeCap(cstore ChainStoreAPI, msg *types.Message, maxqueueblks int64) (types.BigInt, error)

func GasEstimateGasLimit ¶

func GasEstimateGasLimit(
	ctx context.Context,
	cstore ChainStoreAPI,
	smgr StateManagerAPI,
	mpool *messagepool.MessagePool,
	msgIn *types.Message,
	currTs *types.TipSet,
) (int64, error)

func GasEstimateGasPremium ¶

func GasEstimateGasPremium(ctx context.Context, cstore ChainStoreAPI, cache *GasPriceCache, nblocksincl uint64) (types.BigInt, error)

Types ¶

type ChainStoreAPI ¶

type ChainStoreAPI interface {
	GetHeaviestTipSet() *types.TipSet
	GetTipSetFromKey(ctx context.Context, tsk types.TipSetKey) (*types.TipSet, error)
	LoadTipSet(ctx context.Context, tsk types.TipSetKey) (*types.TipSet, error)
	MessagesForTipset(ctx context.Context, ts *types.TipSet) ([]types.ChainMsg, error)
}

type GasMeta ¶

type GasMeta struct {
	Price big.Int
	Limit int64
}

type GasPriceCache ¶

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

func NewGasPriceCache ¶

func NewGasPriceCache() *GasPriceCache

func (*GasPriceCache) GetTSGasStats ¶

func (g *GasPriceCache) GetTSGasStats(ctx context.Context, cstore ChainStoreAPI, ts *types.TipSet) ([]GasMeta, error)

type MessagePoolAPI ¶

type MessagePoolAPI interface {
	PendingFor(ctx context.Context, a address.Address) ([]*types.SignedMessage, *types.TipSet)
}

type StateManagerAPI ¶

type StateManagerAPI interface {
	ParentState(ts *types.TipSet) (*state.StateTree, error)
	CallWithGas(ctx context.Context, msg *types.Message, priorMsgs []types.ChainMsg, ts *types.TipSet, applyTsMessages bool) (*api.InvocResult, error)
	ResolveToDeterministicAddress(ctx context.Context, addr address.Address, ts *types.TipSet) (address.Address, error)
}
