Function opcodeDepth

txscript/opcode.go:1294–1297

opcodeDepth pushes the depth of the data stack prior to executing this opcode, encoded as a number, onto the data stack. Stack transformation: [...] -> [... ] Example with 2 items: [x1 x2] -> [x1 x2 2] Example with 3 items: [x1 x2 x3] -> [x1 x2 x3 3]

(op *opcode, data []byte, vm *Engine)

// Example with 2 items: [x1 x2] -> [x1 x2 2]
// Example with 3 items: [x1 x2 x3] -> [x1 x2 x3 3]
func opcodeDepth(op *opcode, data []byte, vm *Engine) error {
	vm.dstack.PushInt(scriptNum(vm.dstack.Depth()))
	return nil
}

// opcodeDrop removes the top item from the data stack.
