Types ¶

type Result ¶

type Result struct {
	// Accepted is the success state of the transaction.
	Accepted bool

	// Message gives a change to the execution to explain why a transaction has
	// failed.
	Message string
}

Result is the result of a transaction execution.

type Service ¶

type Service interface {
	// Execute must apply the transaction to the trie and return the result of
	// it.
	Execute(snap store.Snapshot, step Step) (Result, error)
}

Service is the execution service that defines the primitives to execute a transaction.

type Step ¶

type Step struct {
	Previous []txn.Transaction
	Current  txn.Transaction
}

Step is a context of execution. It allows for example a smart contract to execute a given transaction knowing what previous transactions have already been accepted and executed in a block.
