Types

type Context

type Context struct {
	BlockHash   common.Hash // Hash of the block the tx is contained within (zero if dangling tx or call)
	BlockNumber *big.Int    // Number of the block the tx is contained within (zero if dangling tx or call)
	TxIndex     int         // Index of the transaction within a block (zero if dangling tx or call)
	TxHash      common.Hash // Hash of the transaction being traced (zero if dangling call)
}

Context contains some contextual infos for a transaction execution that is not available from within the EVM object.

type Tracer

type Tracer interface {
	fakevm.EVMLogger
	GetResult() (json.RawMessage, error)
	// Stop terminates execution of the tracer at the first opportune moment.
	Stop(err error)
}

Tracer interface extends vm.EVMLogger and additionally allows collecting the tracing result.
