ErrNilStatusMetrics signals that a nil status metrics was provided

var ErrNilTransactionCostHandler = errors.New("nil transaction cost handler")

ErrNilTransactionCostHandler signals that a nil transaction cost handler was provided

Types

type NodeApiResolver

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

NodeApiResolver can resolve API requests

func NewNodeApiResolver

func NewNodeApiResolver(
	scQueryService SCQueryService,
	statusMetricsHandler StatusMetricsHandler,
	txCostHandler TransactionCostHandler,
) (*NodeApiResolver, error)

NewNodeApiResolver creates a new NodeApiResolver instance

func (*NodeApiResolver) ComputeTransactionGasLimit

func (nar *NodeApiResolver) ComputeTransactionGasLimit(tx *transaction.Transaction) (uint64, error)

ComputeTransactionGasLimit will calculate how many gas a transaction will consume

func (*NodeApiResolver) ExecuteSCQuery

func (nar *NodeApiResolver) ExecuteSCQuery(query *process.SCQuery) (*vmcommon.VMOutput, error)

ExecuteSCQuery retrieves data stored in a SC account through a VM

func (*NodeApiResolver) IsInterfaceNil

func (nar *NodeApiResolver) IsInterfaceNil() bool

IsInterfaceNil returns true if there is no value under the interface

func (*NodeApiResolver) StatusMetrics

func (nar *NodeApiResolver) StatusMetrics() StatusMetricsHandler

StatusMetrics returns an implementation of the StatusMetricsHandler interface

type SCQueryService

type SCQueryService interface {
	ExecuteQuery(query *process.SCQuery) (*vmcommon.VMOutput, error)
	ComputeScCallGasLimit(tx *transaction.Transaction) (uint64, error)
	IsInterfaceNil() bool
}

SCQueryService defines how data should be get from a SC account

type StatusMetricsHandler

type StatusMetricsHandler interface {
	StatusMetricsMapWithoutP2P() map[string]interface{}
	StatusP2pMetricsMap() map[string]interface{}
	StatusMetricsWithoutP2PPrometheusString() string
	EconomicsMetrics() map[string]interface{}
	ConfigMetrics() map[string]interface{}
	NetworkMetrics() map[string]interface{}
	IsInterfaceNil() bool
}

StatusMetricsHandler is the interface that defines what a node details handler/provider should do

type TransactionCostHandler

type TransactionCostHandler interface {
	ComputeTransactionGasLimit(tx *transaction.Transaction) (uint64, error)
	IsInterfaceNil() bool
}

TransactionCostHandler defines the actions which should be handler by a transaction cost estimator
